It's no good buying a car like this where you'll be spending thousands just to get it back up to scratch and to the condition that you'd be happy with. Seems like there's soo many problems, the amount of money
Think about this way: spend $10k on a car like this and pay about $4000 (if not more) to get it up to road worthiness and mechanically A1, plus future problems from a neglected car. Totalling $14000 to get it on the road.
OR spend $13k on a good condition, well looked after example which you can drive and start modifying straight away if you want you can also get a major service done for peace of mind.
Another suggestion is to ask a well known workshop from your area to inspect the cars you
At the end of the day everyone here is speaking from experience and their friends experiences, and suggest you should just wait and a good condition one will come up eventually.
Hope this helps
