The radiator needed replaced every 3 years.
The water pump needed replaced every 4 years.
I had to replace the upper ball joints every three years.
I found that the car held up extremely well even though I drove it hard.
I drove the car in kansas city as a taxi the whole time that I owned it.
I drive extremly hard, always pushing the car to its limit.
Many times I have hit speed bumps at 70mph with no problems.
At 600 thousand no joke I was still getting 19mpg.
I allways ran steel belted radials that were 225/70/15 instead of the original 205/70/15.
The car was extremly quick and would always light em up.
Uh huh. Your car made it to 600K miles with nothing more than water pump, radiator and ball joint replacements. Yeah that's believable.
For this car? 500,000 miles and its just breaking in. I've even seen the 350 4 barrel have 900,000+ and it's still on the road. These are not like the 4 cyl's you get nowadays. I have one and its at 607,000 and running strong as ever.
Great car.
I used to drive taxi cabs, and it is true that half a million miles would not be unusual at all. 600,000 would normally be about the time we gave up on a car. Here I'm speaking of 'real cars' like the Caprice or other full size full frame rear wheel drive cars.
We also used smaller front drivers like Plymouth Acclaims and Buick Centuries as 'throwaway' taxicabs when we couldn't find a good big car cheap. These only lasted maybe 200-250,000 miles - good runabouts, but obviously inferior to a real car.
