300ZX TT VS 3000GT VR-4

OK well i finally got some money ( tax returns) and im thinking of getting a new old car.. well its between those two i guess.. can anyone tell me the goods and bads of these two cars.. ex how much for gas, parts, maitence, better for higher speeds.. more easy to mod.. all that stuff any info would help out a lot... also if you know of any other cars that are under 6 k that are rare or fast. you know what im looking for.. thanks people

for 6k thats not enough to buy and make those cars u mentioned fast not to mention maintenance is a bitch on them, but if i were u i would look into some kind of a hybrid swapped car ie. rx7 v8, foxbody ls motor or turbo B, H or Kswap civic for that price or even some kind of quick fbody good luck with ur decision.

i found a few 300zx's for 4k and with the other two k i can just have bolt ons.. its already twin turbo so for me thats ok with me. i can just tweak the psi and change some internals to handel the power jump. and like i said.. these cars are sexy.. you see way too many civics round here.. not too many 300's and the rx7.. hard as balls to find in good condition.. i tried.
im still looking for something good. i guess watever comes up thats nice ill take it..

thanks for the input man
