Opinions on whether to buy a second SVX??

[sowise]

I currently have a white pearlie sitting in my driveway that has a blown head gasket that I just haven't gotten around to doing much about yet. I had been considering buying a low mileage engine from ebay or some such place so I could take may time and do one up right and the other one so I can still drive the car. Anyway, the cost of most of the engines I have looked at is anywhere from $800-$1200 shipped to my residence. So I did a search and I have found a semi local SVX for sale asking price is $2K. I went and looked at it and checked it out as well as I could let me describe it a bit...

Ok it is a 92' Black LS-L with 99k miles pretty much everything on it was stock. The paint has some typical age blemishes and some minor dings like edge of the door with surface rust starting and the hood has a couple pits and scratches (I would go to fiberglass hood anyway) Interior was really pretty good shape everything seemed there no noticeable tears or splits in the seats, carpet or headliner. I popped the hood and noticed it has the JDM engine cover. I sniffed the coolant reservoir for any trace of exhaust fumes but didn't smell anything but coolant (good sign) checked the oil seemed clean and ok. there was some oil on the valve covers but it really wasn't all that bad but there was also some fresh looking oil on the passenger side valve cover the began to smoke after I drove the car. Anyway I go to start the car and the battery was dead also notice the battery was not strapped in there was nothing holding it the engine bay but the cables. So the useless sales guy jumped it and that is when I saw the CEL but I wasn't too worried since he admitted it was on before I drove there. (He just didn't know what it was on for). So I go to take it for a test drive and the fuel gauge is well below Empty I was thinking how great of a test drive am I gonna get out of this if it doesn't have fuel? But I drove it up and down the local highway a few times (brake warning light came on everytime I hit the brakes assume the brake tail light was out and noticed a rear end wobble at times which I believe to be the wheel bearings but I didn't hear any real noticeable noise but it would kind of come and go. I know the brake rotors were rusty and who knows if they are warped or not? So I pulled into a parking lot and did a couple of figure eights looking for some potential binding issues but it actually did great at full steer with no problems and the FWD fuse was not in (I checked before leaving). So I took it back to them not completely impressed it had a funny feel to the ride quality which could be in large part to the bearings but not completely sure. After I get back to the dealer I pulled the panel and began to check the engine trouble codes and all I could get out of it was code 11 (crank angle sensor if I remember correctly) but if there were more faults I wouldn't know because the battery died right after that. So I am wondering what you all think? They are asking for $2000 and it would be nice to have 2 SVX's so I can use parts from both for upcoming projects. So I ask is this worth it? Even if I buy it and the head gasket is blown on it or the the seal leaks require immediate attention is this a good buy? I know it comes down to a personal choice but my thoughts are 1.) I get a spare engine without having to turn in a core. 2.) I don't have to get the white car painted black which I had originally considered. 3.) I will have spare parts from the bad engine to install on the new unknown i.e. crank angle sensor as well as any other knick knacks.
I just want to hear from those with experience to see their take on it all.
