Looking to purchase an escape - have question

[k24accord]

morning guys

i have been doing extensive research on the escape's, as i am looking to purchase one for my mother. she currently owns a 2005 ford excursion 4x4 limited and is looking to downsize due to budget constraints. i found a 2007 escape XLT 2.3L FWD with 57k miles (carfax shows it was a fleet vehicle, hence the high mileage) and the local ford dealership is asking 10,500 for it. i was hoping to talk them down to 10k OTD and was planning on test driving it this weekend. my only concern is the higher mileage.

with that said, here's a few questions i have

1. should i be concerned about the mileage being that high?
2. what things should i be looking for when test drive the car?
3. is the listed price and my offer fair/good?
4. how reliable have these cars been for you guys? any common issues?
5. how expensive are these cars to maintain?

thanks for the help guys. i really like these cars lookswise and from the pricing ive been seeing, its alot of car for the money.
