I'm just curious, not that I'd actually do it, but what would be the biggest mod to do to a 98 gtp with 170k on it. I mean it's in good shape as far as everything goes for being a 15 year old Ohio car. The engine runs fine and the tranny doesn't show any problems. I'm just curious. My retarded friend keeps trying to get me to dump a bunch of money in it. His reasoning is "All engines go at some point, so you might as well make it blow going fast" lol
