Take it slow. Put some new brakes, tires and reliable parts on the car, run it until you can't go any faster in it. Save your money, you will need it if you turn into a track junkie....

He might also want to consider something used for a lot less. Maybe he'd enjoy a 350z or s2000 for $12-16k? He could keep the subie.

Thank you for the suggestion, that's exactly what I suggested to him since a used 370z is still pretty expensive. There was a lot of s2k out there at the track dominating faster cars that day. He used to have mix feelings about convertible pocket cars esp a Miata even though he knows it's a great track car. I heard him mentioning a C/R but it cost quite a bit still. I told him all it really is the same thing with a body kit. He also made a comment about how much he didn't like the 350z when he saw my 370z but he said how much of a better job Nissan did with our 370z. He saw a Nismo 350z at the track that day and also fell in love with it.

In all seriousness he has every intention to keep his 2003 WRX because it's all paid off and it's not worth much to sell. I think he just wants a nicer car to drive that can also be an upgrade to his current set up. He was very impressed how well my car did at the track both handling and has speed. His car on the other hand aside from misfiring which I helped him fix - I think just need proper maintenance, he doesn't think it holds the road as well as a car that was designed as a sports car to begin with. He's seriously thinking about brakes, suspension, all these upgrade but I told him if he goes down that path, make sure you already 100% love that car and won't regret anything and also the and also the same amount you put in you can't get something else with a better value.

i agree, maybe get a boosted s2k... or maybe a 135i if he wants a turbo and a newer car.
