Alien - Since you're in GB and the truck is in NY, I assume that you were just passing the link along as opposed to being the seller....
It looks like a Savage XL with a CEN Genesis body and an Ofna engine.
The seller mentions a Revo (Traxxas) radio and receiver, but does'nt show it - nor does it look like the receiver has been installed cuz I ain't seeing no antenna.
My 2cents - From time to time I've bought a couple of Savages off of eBay.
At current price you're looking at $180.00 - $200.00 incl S/H, which is about the going rate on the bay.
If you buy it, expect that you'll need to buy parts or add some stuff.
For example, the seller didn't mention a battery or a failsafe - so you might be needing those.
My personal experience is that most sellers exaggerate the condition of the engine.
I'm not saying this guy is - but when I buy used, I'd rather expect the engine to be toast and be pleasantly surprised than the opposite.
I can't tell if it has a pull start or a roto-start backplate on it.
If it is a roto-start, you'll need the roto-start + battery + charger (unless you have those already)
Also - don't be shocked to find that the diff's are worn out or abused.
I'll also agree with heathW, it looks like it was cobbled together and didn't start out life as an XL - hence my mentioning the diffs.
