I hadn't really thought about this, but when I was at the Kubota dealership yesterday to buy grease, a third grease gun and the radiator genie, I asked the parts guy how much the M5 was. He told me that a reasonable rule of thumb is around $1k per hp. The M5 as it sat was up in the $95k range.It’s ok to have a pair and a spare…that applies to EDC as well as it does tractors. I know what you mean. I am always eyeing an M4…but for now I will not so much as even open the cab…as soon as I get in and sit down we both know it’s all over.
