Go for a later model. I think that in 2005 they changed engines from the WC1 to the NE5. It has better cooling and is a lot more durable than the WC1. I have a 2007 model with 76 miles on it for sale locally for $950. Here is the key question. Ask the owner how fast it will go. If he says more than 27 -29 miles per hour, he has removed the restrictors, and you are headed for a rebuild. The oil capacity of that little engine is only 8 ounces. Look for Whizzer Paul on Ebay as he knows the little machines very well! Merry Christmas to all!!!!!!!!!
