I will be picking up the machine at the first of the week for demo. It is a used 2005 machine with around 700 hours.Has Cab,heat and Air. I think it can be purchased for 40k with a couple buckets and a hyd thumb. Thats about 25k less than new. I have never used a Cat mini ex. Looking forward too it. Any advice on pros and cons about the machine and what too look for as in potential problems please speak up.
