Re: The greatest car of all time? Hellz yeah The Rx7s are really nice, but to be honest any of the jap. supercars are, i mean who would be pissed if they had to have a 3000gt vr4, or a 300zx, or ever the very expensive supra, i mean the rx7 has some great looks and some mad speed but they are proven to be unreliable but i have heard once you take some steps to cool them down a.k.a. intercoolers, raitors, bring a ice pack were ever you go they become a extremely reliable car to drive. ok thats my take on it.
