about to buy a 2000

am about to buy a 2000 sedan with 86k miles. Drove it yesterday and it ran great...the AC not cooling its best, my guess is low on R134 and when shifting between reverse and drive I feel the typical thump, like a bad mount. Anything else I should be in lookout for?

ask when the timing chain was last replaced

he didnt have a clue...I just bought it so is there a sign I should be looking for when its going bad?

you'll hear it

Well congrads on the purchase. At 86k you may encounter some typical problems, such as the timing chain mentioned above me. Any time you buy a car, I recommend changing the oil immediately, unless you know without a doubt it was changed very recently.

replace the timing chain before it breaks, if you let it break it can, and most likely will cause valve damage
