Marketing idea - gift cards!
With holidays here how about offering people gift cards? Say an 'oil change' or 'tune up' or 'breaks job' or general $xx amount? Idea is someone can buy this for their friend / relative who they know needs car help. That person would then redeem it and it would apply as store credit to the job. The only issue is how its worded or marketed as there are some states that have laws where unused gift card balances can be redeemed back to cash. Probably best to NOT call it a gift card but store credit. DYOAI research
