2008 Cadillac CTS 4dr Sedan w/Direct Injection (3.6L 6cyl 6A)
I bought my 2008 CTS with 300 HP DI engine and I swear it feels like an 8 cylinder. The handling of this car is like a luxury-sports car, which is much better than the 2004 350 ZX I traded in. I've got just over 1200 miles on it and it is still as tight and responsive as the day I drove it off the lot. I talked my wife into this car and she is happy I did(it was her 350Z). I got every feature available.
Navigation, Rainsense wipers, V6DI, remote start, headlights that turn with you (I thought this was just a gimmick, but it really is nice). I am most impressed with the rainsense wipers. This is the next generation after intermittent wipers-truly amazing. Of course I am a gadget nut, so I like all the neat
I can't think of any suggested improvements yet, but I have only had this car 6 weeks, and still learning to use all the neat options.
