This company is definetly a scam. We paid them over $1200.00 for them to rebuild our engine in March 2009, in October 2009 the "rebuilt" engine went out. We tried contacting them since we have a 5 year warranty. And the phone number was disconnected. Through research we found they changed their name from Best Engine Exchange in Mesa to Engines RX in Phoenix. The new company won't warranty the engine since they only purchased the "assets" of Engine Exchange. How convenient! We all need to help each other in this matter in getting our money back. If nothing else atleast get these people out of business for good, so they cannot continue taking advantage of others and taking their money.
