If you are selling autoparts the best way to do that is on ebay and craigslist. Having a website is great, but you have no traffic and nobody to sell to until you build the business.

If you want to start a website, check out pagebuzz.com, they do it for jus $20 a month and they run the website buzztrader.com which is a big classic car classified. I am sure they know your market and can help you get started.

Running a good ecommerce website takes years to get right. You can't just add parts and expect to sell them like you will on ebay. It is something you should look into further before jumping in head first.

The website option is good and not that expensive. But it will take a long time to earn any cash with that model.
