fyi- i have seen a number of auto shops on groupon now and living social live.

I think having an online reminder system might be good - instead of the sticker on the windshield - send the customer an email to let them know about time to get an oil change and perhaps offer other maintenance items as well

The reminder system is a great suggestion. Reminders could come in via email or text (at the customer's discretion). This also highlights the potential for recurring revenue in this simple model.

I'd pay $5000 to see that idea happen. 50/50 ownership with the coder/designer. And i'll pay for PPC to market it.
