You really need:

No rust to start with. It'll start to rust as soon as you hit your state line anyway. (Sarcasm)

DOCUMENTED PROOF of timing belt replacements on the V-6 engines. If you don't get it, you're going to need to do it. It's a 60,000 mile maintenance issue.

DOCUMENTED PROOF of the crankshaft bolt having been replaced with the latest updated part number. Part costs next to nothing. Broken part can cost you a LOT.

Here's another tip. When you look at a car on EBay, and the seller lays out documentation in a photo, and one of those documents pertains to Yokohama tires, yet the vehicle has Michelin tires on it...they don't really care what they are selling you. Good catch!

At $2500 and climbing, I'd probably look for something newer (later models are much more comfortable and just as capable), and trade higher mileage for better service history, per above.

You came to the right place to ask, though. Glad I found this place!
