Hey, wait a couple of weeks and call the seller back about that 97 PSD. Maybe he'll have sold it by then. For dependable towing I'll stick with an IDI. There's nothing quite like being there when you have to get your rig towed 150 miles from the nice cozy campsite in the middle of the desert to the closest dealer back in civilization, just to find out they can't figure out injection electronics and you're back on the hook again bound to the next town. Oh, just ask me how I know.... No electronic engines ever again for me. Not over the open road. No thank-you sir. I'll stick with a one wire engine. YMMV
