I think the GT Limited Edition (GTLE) is the best car of the game. I have not used the Ishima ST yet, so I cant comment on that. My car is a 9.4 - 9.6 sec car. It is all-wheel drive so its extremely under control (very important in the Race of Champions). Plus its the best car in terms Prestige, where I started with 950 prestige just by putting the car together, and now I have 300 personal and 1190 car prestige (i.e. I have almost 1200 prestige, and Race of Champions only needs 750). I have only raced about 10-15 races with it. So its not from racing tons either. Also, it has insane torque when you add a supercharger 7.0, so it's, by-far, the fastest car off the starting line. And it just plain looks awesome.

Actually...I stand corrected. The Superhauler 750 with an MC GTLE engine is the best car of the game. I now have a 9.1 second car. 0-60 in 2.3 seconds and 0-200 in around 5.7sec. You need to tweak the carb to 12.75 A/F, the camshafts to -15 degrees for the top two (left and right), and -5 degrees for the bottom two, and you should have your NOS setting at around 250-300 lbs/min. You will need the most expensive tyres of the game for this machine to have decent grip. And if you start the game and race everyone, winning every race, you should have well over 1300 prestige by the time you're done (of course you should have the best body kit/interior/etc parts).

Although I'm new here i must say that Baiern DevilSport is the fastest car i made so far. It has 647 Hp and it crosses 100 km/h in 2.1 s. I also tuned the Super Duty Extra 750 to a 903 Hp muscle machine, which needs 2.3 s to 100 km/h. Anyone with good suggestions or questions can email me on: novinc_s@email.si

Baiern GT III ist the fastest and the moust perfect car... It does extremly speeds, ena handeling is perfect... But its almoust imposible to foun. only car that can mach this is 2.0 cdvc... Try it out...

The best car HAS TO BE the Baiern GT III. There are only 7 in existance. When you go to purchase it from a used car lot, it states that there where 3 red, 3 blue, 3 black and 1 gold one ever made. This car can get up to 200 mile an hour in around 4 seconds. You'll notice the difference between the other Baiern cars because it has a front kit that you can't buy (which sucks cause you loose it very easy) and it has solid black lights. If you have any questions, hit my up.
Peace

I would say if correctly tuned the ishima but its only my opinion. I tuned it to make a top speed of about 360 KM/H in 4th gear.

the best car would have to be the ishima super turizmo because it comes stock being able to run a quarter mile uner 12 sec. but it is extremely difficult to find. the new car dealer doesnt sell it at all and the used car dealer only has it in once or twice while you are playing the game. if you see the car sell everything to buy. trust me it will help you out a bunch. The super turizmo is even faster than the ishima WRZ or WRY. the believe that the WRZ is the faster of those 2 so if it comes down to it pick the WRZ. what i do is buy a WRZ then remake the whole engine with all the most exspensive parts and then i fine tune the engine block so that the idle speed is about 650 and the readline speed is about 8750. it works great because my car runs a 11.976 quarter mile or the drag at night. it will beet everyone on the chart but i dont know how to get the 750 prestige points.

I have tuned myself a Emer Nonus Street GT, ripped the engine block out, fitted the car with a built up Emer Street GT2/Baiern GT3 engine, 12" wide rims, huge tyres, sweet tuning creates a nice 720bhp, under11sec drag beast. Or use a Hauler SuperDuty 750, refit the engine then tune the nuts out of the interior advance angles, then optimise the fuel mix. Horsepower through the roof.
