Background - I currently drive an Alfa Romeo Giulia Quadrifoglio. Amazing car. Best I've ever owned. It's a 2019 that's had 0.0 maintenance issues.

In looking for a new car, I wanted something that really felt dynamic above all other things. I don't care about gas mileage. Interior matters, but only to a point (as evidenced by my owning a Giulia).

tl;dr; Caddy is the most dynamic by a margin, higher optioned interior (not base trim) gets it closer to the Germans on interior quality.

Cars ranked in reverse order

RS7 -
Best looking car of the three in person. Absolute stunner. Pictures do not do this car justice in any way. It's also the most 'exotic' or special looking. Which is a plus. I came into this one thinking I'd hate the interior because of the piano black, and stacked screens. I previously owned an S6 that had a pretty boring interior. But the quality of this interior is outstanding. The "tightness" of everything is unbelievable. One small example is the CF trim that's on the 'shelf' above the piano black that runs the length of the dash. It's so tightly integrated, nice subtle touch.

Sound was amazing. Cold start sounded best of the 3. This really surprised me.

Driving - it's super fast. Land rocket. Hooks up great. But you /really/ feel the weight. It's 800 lbs heavier than the 5BW and you totally notice. This was a complete deal breaker for me. It's over-dampened in my opinion. You don't feel the driving experience as much as you're just along for the ride. Best steering wheel of the 3, worst steering feel of the 3.

F90 M5 Comp - The variance of looks on this car in person color to color is huge. The place I was at had 3, and the black one and white one (I love black cars) looked very regular sedan. Snapper Rocks blue or any of the frozen colors, however, completely change these cars. Interior is nice, though not as big of a gap between the Cadillac and BMW that I expected. Seats are comfortable and look cool but don't feel like sport seats, even compared to my Alfa's standard seats, much less the CF sport seats available.

Driving was better than the RS7 by a margin. Though the roughest suspension setting is hilariously uncomfortable and unnecessary, I think they fixed this with the CS. Crazy fast, handles well. Steering numb but not as bad as the YouTubers want you to believe. Still coming from the Alfa, which may be the best steering sedan ever made, it was a noticeable downgrade.

In general both of these cars just felt like very fast business-y cars.

CT5V Blackwing - This car is good looking in nearly every color (the one I'm getting is red on black wheels). Really don't like the standard wheels though, dresses it down to look like a regular GM product - but they're very nice forged wheels. The interior is interesting because of the absolute wild variance between trims and options. I'm convinced most of the people (rightfully) trashing this interior as a Chevy Malibu amalgamation aren't doing so unfairly - so long as they saw it in the lowest, least optioned form. The standard seats and normal non-CF, non-alcantara interior is basic as they come. But if you put in the upgraded seats, especially in the white/silver or camel colors, and get a CF package or alcantara trim, it punches up the interior by a crazy amount. They're doing a disservice to their own car, and likely costing themselves sales by how big of a variance this is.

The sound deadening on the interior is hyper aggressive. You can get more of the raw V8 with the windows down or the back seats down. But in normal mode, it's tightened up to a level I don't like.

Here's where y'all get mad at me. I'm getting an auto. Wife can't/won't drive a manual and needs to drive my car sometimes. I have 3 small kids too.

On driving, it's the most dynamic of all 3. And it is the most comfortable of all 3 in comfort, and the best handling/steering by a margin of all 3. Even with the auto, it's incredibly engaging. It's far more raw than the other 2, and the power is ever present. Power wise it's underrated, stock BWs are dynoing at 630 at the wheels. For RWD I cannot believe how well it puts the power down.

The car sites all ranked this one higher than the other two. I figured it was because they were fanboying (rightly so) over the 6MT. But even without it, I think it's a better driver's car than the other two.

Here's the best, though admittedly weird, analogy I can give on the two German cars: I love photography, but don't own Sony cameras. I own Fuji cameras. Sony will give me better pictures than the Fuji in a lot of scenarios. But the experience of taking is basically pointing a black box at a subject and a computer giving you the best possible result. The Fuji is engaging and involves the photographer - and often gives better results than the Sony because of its character and imperfections that the glass and sensor give that the clinical Sony does not.
 
How do the transmissions specifically compare between the 3?
 
Great write up and comparo bamagrad 03. I think you made the right choice (as an enthusiast driver) and for all the right reasons.

You will enjoy your ride immensely. The Caddy's interior is underrated IMO (and really now) - aside from just being quite nice its highly functional and the seats are just great. I own a 4 but pretty much the same in that regard. I've long lusted after the RS6/7 but never felt it was the car for me (and I do love wagons/hatches). I'm also a MT guy - but even so.

It also feels good to buy American and to know that we can make a car that meets or beats the Germans at their very best.

Love the Guilia too and wonder how much you may miss it....even considering the various ways the 5 BW is an upgrade....
 
Currently an RS6 owner, and your assessment is spot on. Love looking at it, doesn't excite me when I drive it.

When the QV made its autoshow debut, I instantly fell in love, had a real lust for one in Montecarlo blue with fender shields, charcoal wheels, and yellow calipers. Was able to drive one soon after and would have been ok with its V6 given the balanced driving dynamics.

But those first couple years after release were absolutely brutal for reliability, with reported average time spent in the shop approaching 25% (!!) and I just couldn't pull the trigger because of that. You had a good one!

An Avant was my other choice from my BW5. Appearance was the only winner from every other category. I kept telling myself the Avant was a cheap Lambo. Happy with my choice of going BW5 route instead. I'll save my pennies for an Allante instead.

I will absolutely miss the Giulia. Nothing drives like it that isn't a 2 seat super car. It's really hard to explain it how connected it feels. But with the Alfa dealer going out of business in my city, I'm left with flat bedding it 2 hours away for service.

I agree with the American bit. I've owned several German cars because the American options just didn't stack up. Finally they're not only meeting them, but besting the Germans.

I've owned a C63S AMG, an e92 and e46, and a tuned Audi S6.

Yes, the 17 & 18 MY Giulias had crazy electrical issues. Got sorted out by 19. One thing has been consistently good on these from day one: the Ferrari derived motor and the ZF transmission. Both are bulletproof and powertrain issues are rare. Crazy given the turbos are doing 20+ PSI.

I love the RS6 and 7. I just don't think there's a better looking sedan on the road. They have such presence and you don't see them often. Crazy how small body design cues and proper wheels set them apart so much from the A series variants. I wish they'd put that 4.0L V8 in the RS5. I'd give it a look. Can't believe they're going V6 in the next generation of RS6/7. Sad.

In a good way, they're all not noticeable. Meaning they stay out of the way. The Cadillac felt like it had the longest gears, RS7 being the shortest. The BMW I was most familiar with because it's a similar ZF to the one in my Alfa.

The biggest downside of the 5BW is that you can't manual shift with the gear selector. That's my normal driving mode, not paddles, and that's a downer about the Cadillac.
 
I had an RS6, one of the shortest car ownership experiences of my life. It was sexy as hell after I put some new wheels on it and lowered it, that kind of stuff. However, even with an upgraded tune and pushing around 750 horsepower, it just didn't feel special for some reason.

I'm lucky that I have a friend at the dealership I test drove the BMW and Audi at so I could get a real feel for what driving them is like. I don't want to drive like a jerk or take a super long test drive with a salesman who doesn't know me sitting there.

I got to really spend time with these cars. If I went for a quick roll I'd probably own that RS7
 
Even though you're on my ignore list for getting the auto, I clearly think you made the right choice in vehicle. When I went to Spring Mountain I was in an auto 5BW and it really is a sweet transmission. It's fascinating how it can click off seamless, yet wicked fast shifts at WOT.

I laughed audibly :LOL:
 
3 small kids? I got you…

Man if you're like me any time I've had to do three across, you were cursing the heavens. I had to do it once in my C63 which is tighter back there and I thought there were fewer things more anger inducing.
It’s not bad. Trick is getting the narrowest base seats. The Radians on the outside are narrow and the middle Graco Slimfit is too. Think they’re all below 17” wide across.

I can get the seats in about 10-15 mins since I got it down to a science. Middle go in first, center it, then either side go in. I use the seat belts and lock em (pull them all the way out and they’ll ratchet lock). Don’t bother using the latch cuz that’s when you’d cuss your life away.
