We managed to come to an agreement and purchased the car
We managed to come to an agreement and purchased the car we wanted. There was not much negotiation, but the car was well priced to begin with. We agreed to pay $500 additional in order to drive the car away and have our mechanic inspect it. We got a week to report any issues and could return the car for a full refund if not satisfied by any necessary repairs. Ultimately the car checked out and the only problem was a piece of windshield trim that flew off on the way home. We negotiated a $200 refund and got the repair done by our mechanic so we didn’t have to drive the car back to the dealer. So far, so good.
Meets my family needs
This is our second Jeep and choose four door this time for space it’s awesome the family loves it we can’t wait for warmer days and sunshine

Fantastic Service ! Very professional staff
Hi my name is Abdullah Mojedidi and I live in Menifee CA and I just recently bought my beautiful used 09' Mercedes Benz ml350. I loved the color combination from the exterior to the clean interior. All in all felt great on the test drive. Great costumer service and communication by Robert he always got back to me in a timely manner. I happened to show up on a Sunday when my bank was closed and I had no ride to get back to where I needed to go and the gentlemen at Pro X motors even got me some lunch and a room nearby that was very convenient and much appreciated. I'd definitely recommend all my family and friends to Pro X Motors for their next great car!
