I have a 2005 BBB and it is still going. I traded for it 8 years or more. I have replaced the batteries once. Mine is old and has had repairs I am not sure about the 2008's but think they had made major changes by then.
Mine has: only been stuck once - operator error, hauled 400 pounds of corn + 2 people, has only stranded me once - again operator error. If I drive all around the ranch I can put 7 miles on it and it is good. I am in flat country with clay/sand/grabby soup when it rains. I have driven through water deep enough that it came over the floor boards. I have had to stop in the road to keep from running over birds - quiet. I have slept in it (cow down) and don't recommend it - too short. I have pulled cars out of the mud (some people can't follow directions).
Here are the re-occurring issues with mine: brake pads are always wearing out and I don't use the brakes much (just ask people that ride with me), the steering is heavy/hard to turn/big turning radius.
I have driven (I think) a 2015 and it was a vast improvement (especially steering).
Am I glad I traded for mine - YES, would I do it again YES. Would I buy another used one YES. Currently I have a 2005 BBB and a 2008 HuntVe, and a 2010 Honda 4x4 Rancher. If I can't get the chore done with one of these I go to a tractor. All are workhorses.
Hope this helps.
