Our 1997 Club Wagon 4.2L V6 has 206,500 miles and we still use it frequently for our family. We bought the van when it was a year old and since then have only had a few major repairs -- like a transmission tailshaft seal, alternator replacement and some sporadic brake problems. The motor runs well and has decent power for a V6, but it isn't getting the best economy anymore -- about 16 mpg. It still has the original 4r-70W 4 speed automatic transmission. It slips a little in reverse and shudders at stops once in a while but otherwise no major problems. The brakes aren't the best, we tend to go through front pads frequently (every 30K or so).
Very simple & easy to use controls. Plenty of space and decent seats for a long ride.
Improve brake wear-- perhaps go to a bigger set with 4-wheel discs, and change front suspension to double-wishbone to give better handling & tire wear.
