Does anyone have any info on the Mercedes 309D bus? I may buy one and really need some help. I need to know about parts availability, reliability, and expected fuel milage. It is a four cylinder direct injection diesel. It comes with loads of spares; origional parts manuals, parts microfische, various mechanical parts, and it runs and drives fine. Price is $2500 obo. I think he would take less b/c it has been listed for around 8 months. Thanks!
