I'm in a very similar boat to you with my 1600 mate. I've considered selling it many times, and have had offers in excess of $6000 (for an unregistered, rusted to fark, hardly running 40yr old car)... But there's just something inside me that doesn't want to part with it.
Hold onto it I reckon, plod away at it over time, and enjoy it. by the time you're 'finshed' it'll be a 50yr old car, and worth a shite load more (if you need to sell it)
