I owned a STS-4 prior to owning a new 2007 STS-V. The V is an amazing car and it's scary fast! Even looks cool when its standing still. The interior is a step up from my loaded out STS-4. Nice stiching and quality leather is used through out the interior. The surround sound is an amazing feature with some of the best sounds I have ever heard out of a car. The STS-V screams as it goes down the road. I amazing car that I would own time and time again.
The supercharged 469hp 439 lbft Northstar V-8
I would like to have the options my STS- 4 had like adaptive cruise control and the windshield heads up display would be nice too. Maybe even a awd system?
