i'd highly recommend not buying that truck. Please pm me the contact info for that seller and I'll rwad him the riot act for trying to rup you off....
Pk, but serously now, sure looks like it's worth $1500 to me. I say pounce. If you have MORE funds available, then you have the luxury of time and the ability to shop around. However, if this is close to what you're looking for - and your budget is $1500, go for it. Sure it will need a little work, but ANY $1500 truck will. I like it.
