Unless you happen to be in the business of talk radio, chances are slim you'll ever find yourself getting paid just to voice your opinion. But hey, this is the internet. Anything is possible. And the good folk at eBay have just launched a new campaign to figure out which are the most popular cars on the web by surveying regular Joes and Janes. Even better, they're handing around $50,000 in prizes as part of the deal. All you have to do is head over to the promotion site and answer questions about which brand you think is the most tunable, what's your favorite American muscle car and which is the best brand for off-roading, and you'll automatically be entered to win.

So what are these prizes, you ask? For starters, there are around 200 prizes of various worth up for grab, the largest of which is a trip to the 2010 SEMA show plus $10,000 wired directly to your PayPal account. Sounds pretty good to us. You can head over to eBay for the full skinny on the official rules.
