I took my 37" Toro walk behind in to a local dealer here in Virginia Beach last week for a $60 tune up. The mower is 4 years old. I was told it would be ready in about 6 days. I was never called so I called today to check the status and was told that it was ready and that the price for service was $316.00. They replaced a lot of parts and did a lot of work without my approval. I complained (a little) and they dropped one hour of service from the price which brought it down to $251.00. Is this common? I'm new to the business.
