I found a 2002 Explorer XLT with V8 and it has 106k miles. The current owner tells me that he replaced the transmission last year and he is also offering a $500 major mechanical 6 mo warranty (car must be serviced at the garage he usually takes his vehicles for service). I really just need the car for local driving. Should I worry about the miles on the car?? I don't know what to do. It looks like a nicely kept vehicle. I ran a Carfax and nothing showed up of concern. I'm confused!! Can anyone offer any advice? Thanks.
