“I have been visiting this shop for the past several years bringing all of my trucks and trailer for minor/major maintenance and emergency repairs. Communication has never been an issue, even called the owner ahead of time to order parts before even bringing truck. The mechanics are very knowledgeable and every job was completed on time as promised for a very reasonable price. Also working on Saturdays which is a big plus, I definitely recommend it.” – Pelister Bitola
Google Review – Great price
“I don’t want to share this place with any other people. We get a lot of quality work done here on a regular basis; over a year strong and non-stop action. The quality is top tier and solid and we want it for ourselves. Sorry for the selfishness and past due testimony.”
