We have always received the very best service. Jon (salesman) is a great listener and very easy to deal with. The Hargroves’ (technicians) are the best and also the parts department. They were very helpful and gave us lots of their time. Don’t change anything, and keep up the good work! -

It was my recent opportunity to visit your business and meet Shane Smith (Twin Falls location). It was great to have someone take the time to ask questions related to our goals. Shane showed us the models we were interested in seeing.We made our selection and purchase, with no hassle, push or influence.
