I scheduled an oil & filter change "while I wait", because I had a discount coupon and half an hour.
Derek @ the desk told me it was time for the brake fluid exchange which would be only $100.. and would not take long to do.
I had to wait almost 2 hrs and the final bill was $240. I am eating soup for the rest of the month for that 2 hours in their waiting room. If he had been honest, I could have made a better decision for my finances and my time.
