I traded in my 2000 STS with the 300HP Northstar engine for my new STS all wheel drive with the 6-cyl. engine. I had low expectations concerning it's performance, but I am very impressed by how responsive and fun to drive this car is. I have put 2,500 miles on it so far and the car is defect free. The car is the same weight as my old STS but it feels much more light and nimble. Overall, I am delighted with it.
The remote start that also turns on the seat heaters and rear defogger when it's cold or AC when it's hot out. The keyless system with push button start is great. I also like how quiet it is inside, you can hardly hear the traffic around you. The OnStar system is great too.
I'm not that fond of the new body styling. I like the look of the previous generation of STS better. The door ding protective strips are gone too and I'm not sure how this will effect how the car holds up in parking lots.
