In my opinion...gm has yet to hit a home run. yeah they've been able to get on base..but they've always been lacking something important. the GTO has a pretty good interior and has some decent technology in the chasis and has lots of power. However its exterior styling is very bland and at that price point, styling is a very important factor.
They've come to great strides with cadillac as well. However, they still haven't hit a home run their. The CTS is an attractive car on a decent platform. However, the base engine is weak for the price and the interior is still for people in their 50's. I dont think anyone in their 50's would like the exterior styling. So its doesnt go well. The CTS v is also nice...but again..I don't like the interior and for that price I'd rather get an m3. Now give me a nicer looking interior, and the pluses will start to favor the cts.
