Used Car Pre-Purchase Vehicle Inspection

Never buy a used car without first having it checked out. 
A small investment could SAVE YOU BIG!

Carfax is great if you want to know a vehicle’s history. If you want to know what is going on with it right now you better get a multi-point vehicle inspection by an outside third party, hopefully one you choose.

Whether you are buying from a dealership or an individual it is a good idea to get the vehicle checked out. We can meet you where ever you are buying the car, do a thorough inspection and give you a full report. So when you are ready for your next automobile, bring San Antonio’s Best Mobile Mechanic along with you to check it out.
