I tried to find a good rear engine bus on ebay, but the best I can find was in the $3k range, with high miles and no air.
I figured that I can save some time and the cost of air conditioning by buying it built in. I can hardly afford it either, but if I convert it into a veg oil bus, it would save me $$$ every month in gas, so I figured it was a good deal. Plus it's not traditional yellow, so I save on paint, and it's high roof, so I save on raising the roof etc.
I am picking it up tomorrow, and driving it across country. wish me luck
