I've been a reader of GRM for a couple years. I've gone to some track days. I've gone to some driving schooles . This is a pretty classic question, with a twist. I've got 7-8K to put in a car that is both my daily in sunny NorCal, sees track time and fun backroads. I have 3 options.
1) Miata. I've got a 93 Miata with a 1.8 ready to drop in. The car already has 1.8 brakes, torsen diff, rollbar, hardtop, and full FM butterfly for stiffness. I would do all major maintenance , new seals everywhere, clutch, timing belt, water pump, hoses everywhere, cluch, trans seals. Then I'd get MP62 coldside or hotside supercharger for some nice CARB legal power. Suspension: New bushings and some Fat Cat bilsteins, AFCOs or Tein Coilovers. Minor interior work, new seats.
Pros - Maintenance Done, no oil leaks, clean engine bay. Solid Preformer. Paid Cash for everything. New parts. I have lots of Miata stuff on hand, if I need a coilpack I have two in the garage. Cons - It's still a 93 Miata. Worth 1500 to an insurance company. Harder to sell with the mods.
2) Buy a used newer car. Say a Boxter or MR2 or E36 M3, Z3, c4-c5 vette. I would have a newer car that is worh more that 1500 dollars to an insurance company and easier to sell, BUT I would have spent my money and would probably still have some major maintence to do in the next year or so. Whose to say how my Miata would preform vs the newer car. I dont know.
Pros - Newer than the Miata. Newer technology. Newer build quality. Worth more to insurance company. Easier to sell. Paid Cash. Better performance? Better looks/reputation/badge? Cons - Used car, no new parts. Still could have major maintence left to do. Worse Performance?
3) Down payment on a newer car. I could get a Saturn Sky, Z4, RX7, 350z, c5 vette, Boxter. I would have a newer car worth more than 1500 dollars to an insrance company and easier to sell, BUT would have a payment for the next couple years and it would still have some major maintence to do in the next year or so. I do like the Sky, except for the trunk.
Pros - Newer than the Miata. Even newer technology. Even newer build quality. Worth more to insurance company. Easier to Sell. Better performance. Better looks/reputation/badge? Cons. Used car, no new parts. Still could have major maintenance left to do. Car Loan.
