I drive mine 200 to 300 a week, my only car
and I drive the crap out of it, it has 142k right now, new tranny, original engine. Runs 7.5 in the 1/8th and i plan on improving upon that. Its amazing how much abuse the stock engine and head gaskets can take.
the car is in great shape, just needs new drivers seat upholstery and carpet
even though the outside has 4 different shades of primer, and a dark grey fender I still get people stopping me and complimenting me on it (i think its the shiney draglites ) It really really really needs paint though... the original stuff is so thin its getting that surface rust in alot of places. It makes me sad
Once these cars get to this age and mileage they remind me of the aircraft we work on in the Marine Corps, our newest H46 was built in 1977 so every last thing imaginable has allready been replaced at some point or continually being replaced and repaired. You don't win, you just have to keep on top of it or the number of things wrong will just add up and drown you.
So im always fixing something weekly. Still cheaper than a car payment though.
