I have been looking for a side by side to somewhat replace my 4 wheeler. I have located a well kept 2007 Kawasaki Mule 3000. One owner. Adult driven. Engine has been replaced - says $6000 in repairs. Same engine as used in John Deere Gators. No scrapes, dents, broken plastic. Tires will last another couple years. Seat perfect. Roll cage. No windshield or top. Probably can buy it for $2300. Seems low. I do not need to go faster than 25 or 30 mph. People say Mules are long lasting and hard working machines. What should I look for when I test drive it? What are your opinions before I buy this one? Thanks.
