Another car question

[Grip72]

ok, here i go
i need to sellm y car this summer cuz frankly, i keep dumping money into it and the clicks are gettin up there. Anyways, i found a couple 1990 Nissan 300ZX Twin Turbos around here for sale in wicked condition with about 150,000KMS on em each. One is around $13,000 cdn and the other is $20,000 cdn. THEY ARE SO DAMN TEMPTING...BUT i'm in school and its hard to make any purchases, but DAAAYMN, this is one of my dream cars that i could make a possiblity ..and baby 400HP OOOH YEAH. eh hem, anyways. I could either TRY convince my parents to co-sign a loan for that OR just sell my car and get something for around $8000.

Also, my other option/choice would be around a 95 Eclipse AWD Turbo of course...and those go for around $12-16,000. So i need some damn opinions...i really need/wwant a new car but i'm thinkin my rents will just tell me to get something for around $6,000-8,000 because school is well, expensive...HELP ME OUT GUYS AND LADIES
