OT/BMW 2002 Tii Thoughts, Comments, Smart Remarks, I'll thinking about getting one Options

[newto914s]

Hey guy, I just moved to Puerto Rico about a month ago and have been looking for a classic to wrench on while here. I haven't found any 914s yet, but did run into a 73 2002 sitting on the side of the road. I don't know a lot about the cars, but have heard very good thinks(for a Beamer anyway), and think it would fill the 914 void quit well while down here. I haven't bought it yet, and any input would be greatly appreciated.

Here are the specks on the car, after one phone conversation, hope to know more and have pics by Saturday.

73 2002 Tii
47k or 147k
Original FI replaced with a Carb(not sure of type yet)
Owner states the car was running very well until he blew a hose, lost all the coolant and the car over headed. Clams it needs the Head gasket replaced now, but it can be started it with a jump(dead battery) and runs, but will over heat. Also clams he has a Mechanic that can change the gasket for $100
Not sure how long the cars been sitting, but will probably(definitely) need new tires.
Owner lost the key, and has been hot-wiring it to start, not sure if he has the bottom of the steering col um cover.
Rust wise, it looks pretty solid. A little surface rust around the edges of some body panels, but no vi sable cancer or holes(but I haven't really gotten inside the car yet to search)
Original faded white paint
The owners was asking $2300 before the overheat, now is asking $1400. Mentally, I cap non-running cars at $500, unless they are 911s, but I know this car is "the" classic BMW, so I really don't know what it's worth.

So how ever you can help would be great. Is this something I should consider? I'm hoping to get a better look Saturday(with some pics).
How easy is it to warp/crack one of these heads? How expensive is that to repair/replace?
How much for
Ignition switches
Front bumper(it doesn't have it)
How much to reinstall the OME FI?

What I'm hoping to do is get the car running quickly and cheaply (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) Use it as a second/back-up car while in PR. Then fork over the Grand to ship it back to the states, and do the body and paint here. Keep it for a while as my other car with the 914. Between two 30 year old cars, I should be able to make it to work at-least somewhat regularly (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
Thanks guys
