I don't think it would be an over statement to say Ebay is a big bag of mixed blessings. For the most parts especially smaller items I've done well shopping Ebay. However when it comes to buying cars online it's either lose big or break even but almost never a big win. I am not willing to bet my hard earned thousands to win the exception
I did buy a few cars off Ebay but they were never good buys. My best buy currently my 300D found in the local papers.
