Q: thinking of buying a truck with 300K miles,well maintained etc. would it be a good idea?

asked by on

the truck was a rental that is now for sale, would it be a good idea to buy it with such high millage?

My car has 300000 miles.

The thing to look at is this is a full size truck with a small V6 engine size. This engine would have worked harder than a larger V8 engine would have. This does not mean the engine is bad but something to think about. If you look at how good the truck was taken care of is the main thing. Do they have maintenance logs or receipts to show any major repairs and maintenance was done. The mileage is only a concern if the truck was not taken care of. Look for oil leaks on any part of the drive train. You could get a mechanic to do a pre-purchase inspection. This may help you with your decision and may point out a major problem with the truck.
