I posted at the beginning of the thread about my ultimately disappointing experience with what I thought was my dream car - a manual G80 M3 after choosing it over the 4V BW. Well, with several cars and a couple years later, I finally bought a CT4V BW last week.
Steering feel and ride quality are huge wins for the Blackwing. I much prefer the instrumentation and interfaces in the Cadillac as well.
The carbon buckets were comfy in the M3 for my skinny ass though extracting myself from them was always awkward. (I hate the base M3 seats.) The (fancy) seats in the BW are a better balance but I had to get a damn special edition to get the CF seatbacks so they’d look almost as cool as the M3’s.
I do like the look of the G80 more than most but the 4V Blackwing (with the carbon bits
) looks better. I find the sound in both rather uninspiring out of the box. That needs some work.
G80 has a few wins: a much more usable backseat and a bigger trunk, better headlights, and it’s a bit faster but the Blackwing is just overall a more cohesive package and simply more engaging to drive. I like it better.
The biggest factor in all this for me, though, is the manual transmission. That’s why I bought the car. I will split my driving between the Blackwing, an Ioniq 5N and a Maserati Grecale Trofeo. The relaxed, sloppy nature of the shifting in the M3 is very much at odds with how serious, stiff and fast the rest of the car is. The shifter in the BW is almost perfect to me.
The M3 is a good, very capable car but it wasn’t great for me. I’ve driven the Comp with the ZF auto a lot, too. It fits the car better but is not very fun, either. Hope this helps cross-shoppers.
