Often the job is done in ten minutes and you drive on yourself. We always try an on-site fix before towing.
Won't start, dead ignition, empty tank or a warning light: we arrive with a jump pack, diagnostics and a fuel can and look at the car right where it stands.
If it runs again, the hook stays up and you only pay for the callout. Only if nothing works do we load it and take it to your workshop.
