I've dealt with both. I see your in Oklahoma, you may want to look into something a little closer for larger items, shipping charges will add up quickly. Occasionally you find someone with a deal on shipping. I think the majority of the Mustang parts houses use the same vendors; Scott drake, distinctive industries, etc, etc. If you can get the parts for the same price through Dallas Mustang or Mustang parts of Oklahoma, it would be worth the money for a raod trip. Heck, you could come down to Dallas for the Dallas Mustang open house this weekend and save 10% or whatever it was they were offering. That said, both Mustangs Plus and Mustang depot were fine to deal with and I didn't have any problems, I just feel money could be saved not paying shipping. Just my $.02
