The 2002 model year on was a vast improvement from the early model (look for the repeater in the rear view mirrors). RUST!! This is a new one me and I have seen them with 300K - front brakes indeed they are expensive depending how hard you drive them 15,000 miles for pads and double that for discs if driven hard.
Injecters on the diesel they can leak but it's an easy and inexpensive fix if diagnosed early - same engine is used in the Sprinter, 460 G-Class also 203 C-Class and early 211 E-Class capable of monster miles.
We currently use a 164 with the 350 diesel and I have a 163 with the 500 V8 petrol to tow my buggy, I beat this every week and it has never let me down.
PM me the chassis number and I can tell you all about the provenance.
