I have a 325d and a 329b demoes. The 325 performs just like the 329 except it seems to stick better having more weight on the back so the tires dig in better. The diesel burns a little less than a gallon an hour where the big block is like 2. I figure at $3.70 a gallon average the diesel will pay for itself in less than 2 years running 500 a year. I ike both machines, but the diesel is the smarter purchase I believe 100%. Better resale, fuel bill cheaper, no ethanol issues, cleaner burn. Only drawback is you have to tightnen nuts and bolts a little more often due to the extra vibration of the diesel engines...
