My father doesn’t have a lot of money, but he desperately needed specialty work on his truck’s engine. Red mark quoted him fairly, did great quality work quickly, and went the extra mile for my father because he is a veteran. Whenever a business treats my dad this way it almost brings me to tears. Thank you for helping him out the way you did
