Here's a suggestion.
Look in your garage. DO you have one of these Ferraris:
Enzo
F430
F430 Scuderia
SP1
If so, don't spend the 10,000,000cr on the F2007 just yet.
If not, buy one of those cars listed above from the dealer.
Buy race soft tires, tune to your taste.
Race the Ferrari Seasonal event at la Sarthe 20 times, you will have close to 20,000,000cr.
Then you will not be penniless when you buy the F2007.
