I had a 1978 school bus orange corolla that I bought for 20 bucks. It had right at 100k on it and I put 400k on it in ten years of hunting out of it. It finally broke the timing chain after it rattled against the housing for 250k miles. It was so ugly everyone called it the birth control car.

I have three GM vehicles now with a ton of miles still going strong.

My old 04 Impala with the 3800 has 205,000, my wife's 03 GMC Envoy has 240,000 and my 95 Z71 has 210,000. The Z71 started smoking about twenty thousand miles ago and I was about to put an engine it but my mechanic said to pull the rocker covers and check the drainback holes for blockage so me and the teenager made a weekend out of it and it quit smoking a month or so later. Oil was trapped on top of the head and making it's way down the valve guides instead of draining back correctly.
