Thank you to everyone!! As always, I am the recipient of expert service and advice. Thank you for finding the problem with our truck. I do appreciate the time you take to find out what the true problem or problems are. You spared us from a possible catastrophy, and that is admirable as we thought our problem was a misfiring, but it apparently is more serious. Thank you for the clean car, and for always taking care of us and our vehicles. We have to decide whether to do the work, as our car is old, and we are not sure if we will be keeping it. Time will tell, but thank you for the itemized breakdown of cost and hopefully we can come to a decision as to the right way to proceed. You are all the very best and thank you much!!!
