Well you also have to figure out more..
Has he had the car maintained on schedule? if so, by who?
You see him often since he is your neighbor. Judge him, as what you see is probably how that car was cared for.
So if he's a well-organized, cleanly person you would probably be good. If you walk into his garage/ house and its trashed he probably doesn't keep his car kept up.
Ultimately only you can be the judge!
7k is TOO high. especially with the stated flaws. You can find a very nice 98 in that condition for that price. Check portland CL, I see plenty of them for cheap as I spend my summer out there
