Not sure what to say about it... I bought my B250 about 4 years ago for a stupidly cheap price. My biggest complaint is the gas mileage. I think on good days I can get about 11-14 mpg.
I think I've had about 6 break downs in the 4 years I've owned it. Changed fuel pump twice (my fault on one), u-joints, evap core, radiator/hoses, and cat converter/muffler. Funny enough, the core engine/transmission itself is great... It's the little bits on the side that keep it going that seem to fail. It always fires up when those bits work, and the engine never burns oil, and the trans. never slips.
I'd say back in it's day, it was a pretty reliable vehicle.
Edmunds emailed me and wanted an update on this vehicle. I currently no longer own it, but I can add a few things that went wrong. The voltage regulator went out, and on these vans, it's located in the ECU. If you're unfamiliar with that, it's basically the "brain" of the vehicle. Most do NOT have this part located in the ECU. Everything else functioned on the van that was controlled by the ECU, but this one component went out. It costs a substantial amount of money to replace the ECU, and on top of that, you have to get it programmed at a Dodge dealer to your specific van/vin number, and hope to god they still have the machine that can do that. I dug around on the internet and found this is somewhat of a common problem, and you can wire a separate regulator outside of the ECU and bypass it. I bought a regulator for a 1980's model and wired it to the alternator so it could properly charge the battery. The problem was fixed, but doing this causes the check engine light to always be on, because the ECU thinks the battery isn't getting charged, even though it is with the bypassed regulator.
Shortly after, I decided to sell it with the cost of gas being too high at the time to daily the vehicle. Ironically, gas prices started to rapidly drop not long after I sold it, but... oh well. In the end, I'll stick with what I said about the core of the engine. It's pretty reliable there. It never smoked, burned oil, ticked, or knocked. It always fired up even on the coldest mornings. It's just all the electronic bits on the side that made this a pain for me. Towards the end, I think I got most of them fixed, so whoever bought my van probably got a nice deal on it. I may have gotten a dud, so if you find one in decent shape, you might be alright. I'd just ask who's selling what's been done on it.
