What’s the best out-of-the-box eCommerce solution for aftermarket auto parts?

I've been trying to find a decent solution for aftermarket auto parts for a couple weeks now. We're in the retail parts business and compete with companies such as 4 wheel parts, jeep 4×4 center, quadratec, and northridge4x4. We'd like to find an out of the box solution with support for year make model listings, that can be developed into a modern site similar to these. Any suggestions?
