Hard to comment on price Bob, I just bought a similar car for a good bit less- but it was an insider connection- a friend of mine who works at a independent repair shop bought it a couple of months ago from the owner for a song. He did repair quite a few little things on it, and then realized he did not need it and sold it to me for basically what he had in it.
I LOVE my touring, and I've been waiting for one to come available just like the one I bought- cheap and basically solid.
You probably already know the things that can cost you (auto tranny- mostly), pretty much everything else can be replaced or repaired without doing too much damage to the bank account. The double sunroof on my touring is also mostly inop- the front panel seems to work OK, but the rear panel is dead. I have decided to live with it, and just pretend I don't even have a sunroof!! Maybe one of these days I'll dig into it to see how it works and what the problem is, but until then.........
To me it sounds like alot of car for $4k......look around and see what else that kind of money will buy, and you'll probably buy the touring!!! If it were me, and the car has been on the market for a while, I'd make him a lowball CASH offer (say $2800-3000) and see what happens. One of my favorite methods for convincing a seller to take my offer is to wave the CASH around and if they balk, ask them "what would you rather have?- this (wave cash) or this (point to car)......." This method seems to be more successful if there is a spouse involved who has been pressuring to sell the car.
