Mugen or Spoon S2000. Not the fastest out of the list, but they're overall good cars, really nice handling and very good for its class. I've burned a lot of faster cars with my Spoon S2000
No RX7? No Silvia? No Integra, Accord...(The list goes on) Lots of cars could be classified as a "street car," but a lot of the list I would agree as a "street car." I guess my perception of one is different from yours. That's cool though.
I think he only put the tuned ones, like the Spoons, Mugens and Mines...i don't think there were any "special" tuners RX7s...although there should've been...
however even if my favorite isnt anyone of these as i said earlier, i would have to pick the celica off this list b/c i drive an older one in real life.
