Microsoft's Turn 10 Studios recently announced two new add-on car packs for Forza Motorsport 3, both of which will be made up entirely of cars selected by the gaming public.

Starting this week gamers can hop over to sister site Jalopnik to vote from a list of 120 cars. The voting ends Jan. 29 and the car packs hits Live this summer.

While the round one polls have already closed, round two is still alive and kicking. Get over there if you're interesting in having a say in which cars you'll be able to buy for Forza 3 down the line.
