In NFSU2 , at certain points of the career , you could sign special contracts with sponsors that approached you. Every time the player signed a contract , he gained some extra money and special sponsor races.
I'm suggesting a similiar feature to NFS SA.
How it would work?
After reaching a certain amount of RP , some sponsors could approach you to sign a contract. Each contract would give you special tasks for the sponsor that, upon completion, would give you extra money , and maybe even some discounts!
For example :
You reach 30000 RP , and after finishing a race , Toyo approaches you with a contract for you to sign.
Toyo's contract , upon completing the tasks , would give you 2500$ , and a free body part. The tasks are :
1. Complete 3 Circuit races on 1st place
2. Complete a drift race with atleast 700k points.
3. Complete 2 magazines with atleast 4 star cars.
You sign the contract , you complete the tasks , and you recieve the money and you can choose a free body part.
The tasks would have a time limit , if you wouldn't complete the tasks after a week , the contract is lost.
