Performance upgrade on new car

[robin_nerf]

I have a Opel Corsa with all level 3 stuff on.

But now i want to build a Toyta supra, but when i go to the performance shop, i can buy all the level3, but should i buy the level 1 and 2 before i buy the level 3, or thoose the level 3 make the same thing? (so i just need to buy level 3?)

you shudl buy lvl 1 and 2 for all except NOS, turbo, and tires, the rest you should get lvl 1 and 2 and 3 because you have to get all the necesarry parts.
