1 /5 Shelley Solomon: I think the other reviews are probably fake. These guys told me theyd arrive at 5, then moved to 5:45, then moved to 7:45. They actually showed up more like 8:30. After diagnosing the issue, they wanted over $900 for sparkplugs. Towed it to a real mechanic because I wasnt going to pay that insane price anyway. They revealed that this was a misdiagnosis and I actually needed an ignition coil, a problem fixed for more like $150. Despite the incorrect diagnosis, Guerrero Mobile Mechanics will not offer any sort of refund unless you work with them first. I asked them why would I choose to work with someone that misdiagnosed the problem to begin with? They said because once it failed again - having not fixed the original problem- so long as that was within 30 days theyd fix the original problem. So, dont expect these people to have any professionalism or expertise, and dont expect them to be fast, either. Id suggest going somewhere else.
