I've been at my company for 19 years and we've been using Spence and Frye GM Specialist since I've been with them. They have been our ONLY vehicle maintenance company. They pick up our units and drop them back off. They put aside other work to work on our cars in order to keep our business running. Spence and Frye GM Specialist has kept our entire ambulance fleet running. Just try them and you'll cease your shopping around!!
