Perceived Value


Look at this picture carefully. Here in Maine, we have a lot of "creature migration" during the fall in preparation for the winter. This rodent made a home in this air cleaner housing. The customer came roaring in with the throttle cable stuck open. The housing and above the housing was filled with matting & straw. Your vehicle needs to have a professional look under the hood at least once a year to try to detect this potential problem.


What is true value? Is it when something is the cheapest? Or is it what you get for your money? When it comes to the automotive industry, here are some thoughts to consider.


In order for a repair shop to do things cheaper, what are you as a customer giving up? There will always be someone that can do it cheaper. Does the repair shop have experienced ASE certified professionals that are compensated properly or people just leaning on your car? Does the repair shop carry garage liability insurance in case something happens to YOUR VEHICLE? Do they keep up with today’s technology? Do they attend training? Do they use the highest quality parts or just the cheapest parts they can buy? How long do they stand behind their repairs? (Until they can't see your taillights or for at least a year?) Do they offer above and beyond services like shuttle service, loaner cars, service reminders or courtesy checks?


What is the value of value to YOU?


For 46 years we at Horsepower Autocare have pledged to you our VALUED customer to provide QUALITY repairs at a VALUED price ALWAYS.


"Thank you for the excellent service. What a secure feeling it is for me. Women alone are such an easy target and I appreciate you very much." D.D. Windham
