Yes they are a 5 star shop but be forewarned, they are busy! I always take that as a good sign, if they werent good no one would want to go to them. But because they are such a good shop they have a wait list on just looking at your car. Its worth the wait. So to the actual review. My wife and I both have diesel vehicles. We bounced around a few shops and never really found a place we felt confident in. We happened on Pro1 based on a suggestion/recommendation from a family member, and we couldnt be happier. They have taken care of my Excursion that had been sitting for about 10 months. It runs perfectly and is so reliable I have no issues taking my kids in it. My wifes F250 has had new fuel injectors and now almost the complete front end is being redone. Pro1 has also fixed issues another shop claimed to, and has had zero issues prioritizing repairs based on my budget (ie. Dont drive it until this is done, this is ok to drive for a bit but will need to be done, and keep an eye on this eventually it will need to be fixed). They also were willing to hold onto my wifes truck until we could afford the repairs. No pressure or making us feel bad, just allowing us to make payments and having it ready to roll when we finally paid off the balance and were ready to take it home. If you can handle the wait to get into them, you likely will not regret it. Its a shop that has integrity and takes care of their customers. I can not recommend them enough.
