"Very impressed with the help and service that was provided. Pricing was very reasonable and welcomed, especially after receiving an exorbitant quote from a major dealership. Would recommend JAC Auto Services and will not hesitate to utilize their services in the future."

"What a great family business , well worth having a chat with James for your motorhome improvements/ problem's."
Mike Taylor
"My 2006 Nissan Navara 3L turbo broke down in Hamilton on December 17th, and AA recommended this place saying that they have very good expertise with diesel injection systems. JAC was the only firm willing to look at it, since it was close to Christmas. By the end of the week they had diagnosed the problem in the injection pump, given me a fair estimate of the cost to fix and said it would be ready by January 8th or 9th. Turns out they had it fixed with a new/refurbished pump by Jan 7th. The invoice had good detail, and the new pump has a 12 month warrantee. My truck was safe with them over Christmas and now has more power. Nissans with the ZD30 engine have this problem regularly, before 400,000Km. James was good to deal with, quality job, good at remembering details."
