Caddy made the CTS-V Wagon in 2011-2014. There were ~2000 sold. In a straight line, the automatic tranny version was (slightly) faster than than the coupe or the sedan bc of its shape. I think there were <400 MT versions sold. I saw one at a track event at VIR in 2013 driven by a Novice student & I gave him kudos for bringing it to the track. I always wanted one but couldn't afford it when new. A really good one these days with low miles goes for up to $100k. One of the probs with the MT version was it was not up to the torque the engine put out so it was a common point of failure whereas the AT was relatively bullet-proof. If Caddy came out with a Wagon 5BW, I'd be the first in-line to get one. I love wagons & hatches.
Back in the day, I had a 2005 Subaru Impreza WRX STi. I was on the annual Tri-State Subaru Owner's Club charity run in 2007 & was able to tour the Subaru headquarters in Cherry Hill, NJ & met the then CEO, Tomohiko Ikeda. The year before, they had brought back the Impreza wagon. I told Mr Ikeda of they made an STi version, I'd get one immediately. He smiled & said, "Keep your eyes open for good things to come," & left it at that. The next year, the new STI came out as a hatch & true to my word, I went to 3 different Subbie dealerships to get an allocation. I was one of the first in the northeast to get a 2008 Subaru Impreza WRX STI.
