A friend of mine has just sold his for £16500 but that was fully restored and one of the best you will ever see,he paid £9500 for it 2 years ago A solid example requiring minor work go for about £6-8 k,mint ones are £10-12k and ones for restoration like my example are around £2-4k depending on state.
The prices for mk1's are rocketing though and the car above will be worth £25k in 4 or 5 years if kept like that.The beauty with mk1's is that even mex's and rs2000's dont really lose money if they have different engines,gearboxs or axles in them,as long as done properly,and that vauxhall engine in the car above sounds the dogs bollocks.
