The Kumho Tires Grassroots Motorsports $2007 Challenge

Presented by eBay Motors and CDOC.

For the 8th time, we challenged our readers to buy, build and race a car on a budget. And once again, they rose the challenge at the $2007 challenge, held October 4-6, 2007 at Gainesville Raceway in Gainesville, FL.

As in previous years, the rules may have been simple, but the entries were amazing, with everything from a Chaparral-inspired "sucker" Corvette to a Zamboni.

And keeping with tradition, next year's Challenge budget will be raised one dollar, to $2008.

Believe it

Think Challenge competitors may be guilty of some creative accounting — that no one could really build a high-performance car for a measly two grand and change? Think again. Challenge competitors are required to provide documentation to back up their accounting claims, and we look them over.

Now we’ve put the Challenge-winning Cheaparral Corvette’s build diary online, so you can look it over, too. Start believing.

$2007 Challenge Drag Results (DIY)

Attention all $2007 Challenge competitors!

Since we were rained out on Saturday, we had to cancel the drags. That was a drag. Now, we’d still like to write about how fast your car goes in the quarter mile. We will accept any valid drag strip results slip from 9/1/2007 to 11/1/2007 as a part of this story (but not a part of the official scoring). We’ll post a listing of the results online so that everyone can see how things could have shaken out.

Please email a scan of your slip to Chris@grassrootsmotorsports.com. You can also fax them to (386) 673-6040 or send them via carrier pigeon to:
