I bought this car because it was cheap and had the 3800 engine. I have had Bonnevilles and LeSabres and love this motor! Very glad they put it in a sportier car like the GP. I've had it for two months and I've had to replace the EGR valve because it kept stalling and an o2 sensor, but this is why I got it cheap! The car rides GREAT, even at 85 MPH and I'm sure it could do more but I shouldn't abuse it any harder--it has 145,000 miles! Some worry about 100,000 miles--these cars will run forever. Really. But they do have some issues that arise; make sure you maintain them. One morning I couldn't get it out of park--took the console apart and tied the stupid shifter button down.
