I used auto trader and car fax. By the time I saw the ads most of the elements were already sold. I paid 8k for mine. I have already had to put a ton of work into it as well. I am with other guys. buy one knowing you will have to put some money into it. there was a guy on here just recently trying to sell two of them. search elements on the east coast for sale... I will try to find the thread.
