1998 Pontiac Firebird, 3800 V-6, around 98,000 miles, have had for a year, have installed new spark plugs, wires and coils, new battery, new bearings in rearend. Only issues are windshield has a crack and the dash is cracked as well, radio volume knob acts up at times. I'm an auto tech and have kept the oil changed in it and have fixed everything on it myself. Gets great gas mileage.
