In a word, painless. Dan arrived about 10-15 minutes early and efficiently finished the jobs I had requested. Dan and yourmechanic.com provided me with a much better alternative to leaving my car at a shop the night before and then being without transportation for the entire day.
Jeffrey was a very nice and friendly mechanic. He called to let me know he was on his way to my location within time window given for his arrival. He was prepared with the parts and asked questions about problems I was having to remedy the problem. He has an eye and ear as a mechanic that is helpful in solving a customer's car trouble. I will use him again and will recommend him to other people. He was truly "Your Mechanic."
