I too would not hesitate to buy my tractor or another Montana again. I paid $16,588 for a 4344HST w/FEL. Also got a backhoe, box scrapper, TnT, rock tooth bar at cost. (I checked. For example, the rock tooth bar MSRP at another dealer for $400 I got with my tractor for $275).
I got my rebate to use as the downpayment and 0% financing for the tractor and all the implements.
My dealer delivered my tractor and spent 3 or 4 hours going over every aspect of it and the implements with me. We practiced removing and installing the 3PT backhoe and the scrapper, how to operate every lever and control, went over the dealer prep and setup check sheet together, etc. I view my dealer as my partner. I think the warranty is 3 years but he told me as long as he was the Montana dealer, and I was taking my business to him, scheduled maintenance, accessory and implement purchases, etc, then my tractor was under warranty. All repairs are done at my home, I never need to trailer and unless there's a catastrophic failure, I never have to worry that they will come and take my tractor away for weeks on end. They even came out on a Saturday to fix a hydraulic leak on a fitting!!! Wow!! My tractor is everything I hoped it would be and I am ecstatic that my dealer appreciates me as his customer. Good luck with your new Montana. If your sister has e half the positive experience I have, she and her husband are going to be thrilled with their purchase.
