To bad it's being sold by a dealer (I'm assuming a dealer based on the paper over the floor mats) and not the original owner so you could find out exactly what's been done/not done to it. We bought the exact same car (2003) a little over a year ago from a dealer. One owner, 48k miles, Silver/Gray, V8, for about the same price, etc. 2003's and early 2004's I've now been told had bad transmission fluid in them that was missing an additive. 2,500 miles after buying ours it was getting a remanufactured transmission. ($2,800) A bit later all the cooling plastic parts needed replacement. Don't make the mistake others have made, use OEM parts for that repair. Factory coils that didn't last, replaced them, plugs, etc. A couple other things here and there and we have over twice what we paid for the car with about 62k miles on it.
As others mentioned, hope you get a 'gem' and not the lemon. We love the car itself, just been the worst car I've ever owned as far as getting it to run correctly.
Best of luck to you.
