Why ?? Does everyone always look for the cheapest place to fix a car. This thread is an example of what can happen when you do that.
Best thing to do is find a business that you trust. In the long run you will
get a much better deal.
I have used marks numerous times and never had any issues with them. On two occasions i dropped off a vehicle with a suspected problem, they checked it out and said it didn't need anything. that isn't like a company that is it to rip you off. Another time i had took my truck there to because it died on me (had it in a dealer for the same issue a week before). Marks replaced a part that i had replaced at a dealer the week before. I protested, but mark gave me the old part and said he stood behind the work he did. I didn't have another issue.
I trust Mark and his wife, the people who work there (as far as theft go) may be a different story.
