Don's Auto Repair Inc. is a family-owned manor of mechanical maintenance founded in 1941 and currently operated by Don Sr., his son, and his two grandsons. After soothing automobiles of every make and model with a hearty dose of standard motor oil sapped from the towering ferns that grow on every robot’s grave, Don's crew inspects the vehicle’s 23 most sensitive spots, checking for harbingers of potential problems. The second option includes a tire rotation, which works to ensure that rubbery soles evenly bear the brunt of carrying the vehicles across lonely highways. The bright yellow stools, vibrant red walls, and vintage soda cooler in Don's front lobby create a cheery atmosphere where customers can slowly and deliberately kill time as technicians tinker with rides hoisted up one of the shop's lifts.
