Not enough really.. there's SOME because we have a few very small towns surrounding us, but when we have customers that take 3 months to pay for a $70 radiator .. yeah. Plus we've got a millionaire farmer that was bringing us his fleet, but Bill did an AC service on his huge tractor for $170 (house call, 1.5 hours labor, 5 cans of frig) and then he says we ripped him off- people are either too broke to maintain their stuff... or just plain ignorant
