I purchased a motor for $1100 and paid $175 to have it shipped to my mechanic. This motor was found on car-part.com and it was rated an "A' and even said "very good". I called and confirmed this with orange auto salvage and they said an Allstate insurance agent was with him when they cranked so I went through with the transaction. They gave me a 90-day guarantee on the motor. Upon receiving the motor and installation as soon as the motor cranked it was knocking. I called them back immediately to let them know and they got very defensive saying "that's impossible" basically calling me a liar. I then reminded them of their 90 day guarantee and they said to ship the motor back and they would send me another one. I did as they requested and spent $300 to have it shipped back only to find out that they would not take it and their reason was damage. I have pictures from the shipping company to prove there is no damage to the motor and its in the same form it was when it was shipped to me. It cost me $1275 for purchase and shipping, $550 to have it installed, $300 to have it shipped back and I have not received what it cost for them to take the motor back out. This is very unprofessional. All I ask is that they hold up to their word.
