2003 Chevrolet S10 Truck / Blown Head Gasket Please Read / Tan / 4x4

This was my personal vehicle. I was driving one day and it started acting strange and white smoke started coming out of the exhaust. I was close to home so I drove straight there and put it in the garage. The mechanic said it most likely has a blown head gasket. It has sat in my garage for over a year because I have another vehicle. I have decided I am never going to go through with getting this fixed so I should just sell it.
It also needs a door panel on the drivers side, this isn't a big deal and shouldn't take any time at all to fix when you find one. I just never got around to looking for one.
The only other thing is that it has a dent on the passenger side, most likely from some sort of minor collision but that was before I owned the vehicle, please see pictures for damage.
A few weeks ago I verified that it would still start. I jumpstarted the truck and let it run for about 30 seconds, pulled it in and out of the driveway, everything seemed good.

An eBay user contacted me and suggested that it may not be a blown head gasket but an intake manifold gasket leak instead which he said was fairly easy to fix. I only ever spoke to the mechanic on the phone so I can't say for sure if it is the head gasket or the intake manifold but I am still selling the vehicle as is and assuming it is the head gasket.
