I have dealt with Adsit and they may be less expensive on parts, BUT you will never gain the amount of information from Adsit that you do gain from this site. Adsit does not give you 24 hour service with regards to your cars technical questions. I have been stuck on car jobs at 2 am and posted a question and recieved a reply from the OWNER of this site, within minutes. The amount of money I have saved by hanging out on this site would never compare to the pennies you would save on a few parts.
