Main reason I do licenses is for the cars you get.
Go for all silvers, (All golds requires a lot of grinding and repeating finding the PERFECT line).
If you get all Silvers for a license class you win 2 cars, one for all silvers and one for all bronzes. The cars are worth a bit of money if you want to sell, or they save you money as some can be used in some of the A-Spec races, saving you from having to buy them.
I've finished International C atm haven't been on GT5 in a while, and i've gotten like 21 silvers, 9 golds. I haven't tried immensely to get Golds, but I can imagine getting all golds for the license events will not only give big XP payouts, but also some pretty sick cars.
