Ebay is full of part finished projects that are "90% complete" with the usual "no spare time" or "no place to store" excuses. Whenever I see them I can tell it's just someone that's started something but has gotten so fed up looking at it and spending money on it that they just want shot of it. Look at the amount of people that start resto threads then disappear after a couple of posts. If you're doing a major project you need to have a certain attitude to be able to see it through to the end. My car is an XR3i and I too have spent about £2.5k on getting it where it is now. It sat in my garage for the last six months doing nothing and it's only in the last few weeks I've shown it some interest again and it's only now I realise how close I'd got to finishing it when I gave up on it before. Is it not better to have something to show for all your effort and cash instead of selling/breaking it and buying a boring new motor?
