Wich car is the best to hit 322 kmh

You have been upgrading your car as you go right? cause i believe i got the starter car to 200MPH, which i think is 322KMH, though i have the Digital Deluxe Edition, so i get some very nifty mods for the starting car.

It was very hard, but any car better would do it more easily, i went with the GT-R, which is like 70k give or take, but make sure to have enough for the mods.
