My GP has given me 5 years of great service . I did have a front rotor warpage issue early on and just decided to replace them. Otherwise, just change the oil and other common maintenance. Sad to see Pontiac end its production of Grad Prix's. Love the Pontiac red dash lights.
3.8 engine is powerful and I get 26 mpg driving to work, and not all highway.
Brakes are powerful but I would expect no warp problem as I incurred.
