The nose looks like the later '01-05 piece. Less than 50K miles with a lot of wear on the seats? New top and carpet? Hmmm... sounds fishy like a flood car. Good title? I'd get a CarFax for the hell of it (I don't currently have a subscription, but I'm sure someone here does).
If it drives nice and doesn't blow smoke or leak juices, I'd lowball 'em at $4500 and see what they say.
