That's the plastic model, I have the BX2350 with just over 1000 hours. They don't take much abuse - pretty much every panel on mine is broken or cracked. Then again, it had been abused before I got it.
So, three thoughts for you:
1. If the plastics are in good condition, then someone must have looked after the machine well
2. Be a bit careful once you have it. On mine, which was already very rough, I've broken the rear fender when I used a trailer with a shorter drawbar than I thought, turned sharp and it hit the fender. And I further broke the front hood when I hit the bracket that keeps the hoses tidy on the FEL.
3. Mechanically, they're tough. Although mine's clearly had a hard life, I've never had to do anything mechanical to it, I did the last service myself and the fluids all looked fine.
