I agree...the dealership is there to make money and they are pretty good at it.I would go to a shop that specializes in wheel alignments it will cost far less.
Do you see any reason that you need an alignment when you look at the tires? The last time I did an alignment because the shop suggested it, it actually made it worst and ruined 2 of my new tires. When I took the car back, they only offered to SELL me 2 new tires at a discount.No they offered as I was driving in to the "check-in" area. There was no measurements nor diagnosis. Just a visual thing and the fact that I came in for 10,000 check up..
