Tough question, easy answer: Mitsubishi GTO/3000GT The MR is the better version since it's (slightly) lighter. This car has been killer with a Stage 4 turbo kit. It can have up to 930hp and reach a killer 240mph. I usually jack up the Turbo Boost to get maximum power. Since it's a 4WD car, you don't have to worry about spinning out as much as you have the traction of FWD and acceleration of RWD. Gran Turismo 1 was a thrill ride for many cars. While realistic, it remained very fun. I would STILL prefer GT1 over GT2 and GT3 simply for the fun and all you could do in the game. Every GT since this one became more realistic, and that speed demon of a 3000GT is more softened up and realistic. In GT3, however, you can boost the HPs to more than 1,000 hp. Now anything past Stage 2 NA or Stage 3 Turbo is basically for high-speed battles than twisty race tracks. But those were the days... me and my Mitsubishi 3000GT, beating just about every Special Model car available from Japan. And winning all the while. That's my favorite car. What's YOUR favorite?
