Excellent service. Mechanic had my car up and running in under 15 minutes. Convient home service. Will use this service again.
Had Caleb do a pre-purchase inspection on a Jeep I was buying from Missouri, and the guy was great. Really thorough — found stuff I would’ve missed, told me straight what was worth fixing and what wasn’t. No runaround, answered all my questions fast. If you’re buying a used rig, don’t skip this step. I highly recommend.
I needed a vehicle inspection done for a truck I could be there to see for myself. A thorough inspection was done, the mechanic called and talked to after and a report was sent afterward. I would use this company again.
