I looked at used ones as well... They appear to hold their values very well.
I was seeing some 2-3 years old at about the price I paid for a new one.
Granted, mine is only the 500 model and the only extras I got were:
Roof
Windshield
Trailer hitch including for garden/farm attachments
Rear...
Picked this up in Blue Ridge yesterday.
The primary purpose for this is the wife going around the neighborhood with the cooler....
There will be some yard work with this toy on the 5 acres....
Seriously... I have an MTech... Love it... very heavy duty blade... Looks so nice, I don't want to get it dirty... For the garden stuff, I use a small electric chain saw or a pole saw...
Here is my MTech
