Just looked at your site both as a shop owner and a consumer. First off, you lost me as a consumer that has no knowledge of auto repair.
Why would I or anyone else go purchase a OBD II device to scan the codes and send it to my phone? AutoZone will do it for free.
Now you want me to send this info out and find some one to estimate the repair because it may be a common problem. AutoZone is going to tell you the common problem hoping you buy parts.
And I am having problems now, RIGHT NOW !!! I need answers, not an estimate based on codes that may not fix my problem. Gotta pick the kids up at 3:00. Hey AutoZone guy, I'm not a mechanic who would you recommend?
See where this is going in the fast paced real world?
As a shop owner, I just sent some business cards to the AutoZone guy.
