I have been satisfied with the service everytime I have used Calvert's Express.
It started with a 2002 Honda that had a broken pipe leading into the muffler. I received $300 plus quotes for a new system even though I said the muffler is fine, the leading pipe broke at the coupling from bottoming out on a dirt road. The Honda is old. Calvert's refitted the coupling, welded it together and the cost was $69!!!!!! The Honda is still in use.
I have been a customer ever since and have sent people who have also been satisfied with the cost and service.
