I had the z28 auto, i got the car with 40000 miles on it, really fast car just stock, stereo in it was really good, car ran great up to around 50000 with no problems, then i started to mod it, cam headers, touque converter, and on and on, then it started to have problems, trans went on me soon after, the rear gears, bad break vibrations, the after about 10000 the brand new trans started going, and coolant started boiling after normal every day driving so i sold it, great cars until you mess with them then they mess with you back
