I'm still driving it
'69 Malibu (in sig) I bought it in very rusty but running/driving condition when I was 15. It had a good running 350 2bbl/TH350/2.56 open 10-bolt, 89,000 miles. I drove it for a month when I turned 16 and tore it apart for a "quick paint-job" in my Dad's body shop. 2.5 years later, it was painted 95 corvette "Dark Cloissonne" with white stripes, and had Cragar Street-Stars on it. I finished it with 3 days left of my Senior year in H.S.
All I did for mods, was stock discs up front, and 2-1/4" dual exhaust with glasspacks

. Probably would have run a 15.8-16.0
I have since put a stock 190,000 mile 400 sbc in it (cracked a head on the 350, and the 400 was a good runner) rebuilt the tranny, and stuck a used 3.08 posi 10-bolt out of a '66 oldsmobile in it, and put 4-wheel discs on it. I've run a 15.04, but I think I can muster up a 14.999 out of it before I tear it apart for the LT1 I'm sticking in it
This car is NOT my first car though... first car is my '69 SS I bought when I was 12... no engine in it then, and now. I've owned it 10.5 years and have never driven it
