Ebay's great if you only go for auction items. I personally look at the but-it-now items with suspicion and usually research the price and buy elsewhere. Most of my money for new parts goes locally, supporting local business and jobs, but the hard to get and used items with a low start price are always worth a punt!

It's amazing how many cars seem to fetch good prices and next week are back on again! People must be buying blind and then renege when they see it.

Use PayPal only! And check feedback before risking any cash. Any buyer with a reasonable number of good items on at once is usually a safe bet as well, especially if there is lot of Bellek pottery among the car parts!
