I've got the T230 lwb. 2004. Had it about 6+yrs. It's been great. As has already been said, I have had both sills welded back up. Definitely a problem. This was a few years ago now and the rust is coming through again and it's starting to look tatty. The rear bumper is very similar.
Mechanicaly and electrically it has been sound. Drives like a car. I've got 500ltr upright tank fitted across the bulkhead. Quite stable fully loaded and under braking. Excellent reversing with full load, good gearing.
I think, overall, an excellent machine. It serves me well. The timing belt needs changing at 100,000/10yrs whatever comes first (if memory serves me right!!)
