Jeez, didn't mean to raise the temperature under your collar so much. Sorry if you took my comments in a negative light. They weren't meant that way. And I agree, as I stated earlier, we are way off topic. No insults meant, and none taken.

Now, back to the original topic.
I thought about it some more, and if you (the original poster)don't have the upgrade kits for your cars, you might want to buy the two you suggested. This way you have two turbos and suspension upgrades for both cars. It would give you more options to fiddle with in both cars and make racing them more fun. And it would give you more of a feel for what the upgrades do for the cars. Later, you could get the FnF kit to play with a NOS and have more bodies to swap around. This is what I did, and it made playing with the cars more of an even progression for me.
