Scotty I just got 4 new tires and alignment at my dealer for a volvo s80 2012 I have. Being a perfectionist I hit some medium to minor potholes accidentally just by taking my eyes off the road for a fraction of a second here in NY. Another dealer in my area has the fastline alignment radar detector machine that analyzes a cars tires in relationship to one another as you enter the dealership when you first drive in. It's free. Most dealers don't have it. The dealer also offers a complimentary service to check all fluids, tires, suspension etc. What's your opinion about it if it really doesn't cost anything? Do you feel they are accurate?
