1990 to 1996 300ZX or RX-7 1993 to 1995 do you realise how hard it is to repair old sports cars? I performed many engine replacements on twin turbo rx-7 cars under warranty and it was expensive. Out of warranty $8,000 every time you detonate a Apex seal. I have worked for both Mazda and now Nissan Old Z-32's are getting where they need all kinds of repair before they are safe at high speed too. Sports cars are expensive to insure. RX-7 may get 10 miles a gallon around town and only 17 highway Old Z-32 300zx not all that much better the non turbo can get 21 highway. And about 15 in town. I don't know how old you are or the extent of your mechanical abilitys. Think a much newer car especially if your going for higher education. A small Nissan Versa Or Mazda 3 might be a better choice because it is in warranty.
