Low mileage is nice, but is sometimes overrated.
We were buying a Nissan Altima from friends. Belonged to the friend's mother. Was an 01 with only 26k miles! No rust on the body and sounded great. Then, we got it on the lift...
The front main crossover beam, which supports the engine and front end was rusted right through! the rusted crossmember could technically been replaced, but it was going to cost a lot more than the car would be worth after the repair. Good thing it was friends as the seller, they took it back and donated to a charity for scrap.
I have had two vehicles (including the 04 Tahoe I daily drive now), that had 180k+ miles on them when I bought them. I have not regretted either purchase!
High mileage can sometimes mean more things to fix, but not always. Both high-mileage vehicles I bought had some key work already done on them, because they were actually driven. A lot!!! My mechanic buddy was actually impressed with both the 05 TJ Rubicon and the 04 Z71 Tahoe I came to have him inspect for me.
