search around many have high miles without much trouble, others have had trouble. if you keep up on maintenence and replair and replace parts before there is a problem you will have a long life from your car
also the valve is so small it might not be worth selling unless you really want a new car, best bet in that case is to find a dealer that say is offereing a minumum of 4k on a trade in that is in any shape and go for a deal like that
