Q: I'm trying to decide a good tuning car that is stock and is under 45,000 new not used, and not hybrid must be sedan, coupe or preferably roadster no suvs or minivans and if you suggest something please put reasons and if you can some mods for it like vertical doors, turbochargers, drag slicks, etc.
A: Honda S2000 Nissan 350z or upcoming 370z Porsche Boxster or Cayman BMW Z4 M Coupe or Roadster Acura TL Type S Audi S4 Subaru Impreza WRX STI Mitsubishi Lancer EVO X Audi TT Mazdaspeed 3 Infiniti G37 Coupe or G35 Coupe Mitsubishi Eclipse GT If you want a performance car to race on a track with turns, get a turbo kit, front/back sway bars, strut bars, performance tires, coilovers, shock absorbers, roll cage, and lighten load. Take back seats out if the car has them. A Spoiler for high spees areas. Lightweight rims(wheels) If you plan on drag racing and get slicks, it will not be street legal. It would be legal if you use normal performance tires, but that is worse for drag racing. Lighten the car and install a rollcage. Turbo kit or supercharger would help in acceleration too. A Spoiler. No handling modifications needed for straight line racing. If this is just for show at car shows, then do body kit, rims, tires, sound system, paint, everything cosmetic, including getting the engine cleaned and parts chromed or painted. Hope this helps. Good luck.
