Interesting exchange of comments.
The classic car market is going through the roof in the UK. I recently sold my 1993 Saab 900 turbo “SSE (Swedish special edition, (1 of only 15))” in non-running order, - no clutch left, the coolant tank was overflowing with rust, - and minus its air conditioning unit, to a Dutch collector, who paid me, what I thought was a good price for it. But then I noticed what similar cars were/are selling for on the continent, making me feel robbed! 
He had been asking me for years, upping the price every time.
I realised he’d purchased a “unicorn” off me (in terms of just the chassis number alone, - NOTHING else) bar the 16” deep-dish alloy wheels. Why the big deal about a chassis number when the car is no different essentially to other models of the same spec? He's now got specialists doing a ground up restoration on it, intending to take it to Sweden for the Saab Classic car fair soon. Good for him! 
(nod to Abba ) as I affectionately called her, has gone to a very good home. Saab 900 ‘classic’ turbos and convertibles are fetching silly prices, - and especially in Germany? Anything from €4,000 to €60,000 ?!? 
The later GM Opel/Vauxhall based versions (1994 – 2011) are also becoming collectable and consequently rising in price too.
no worries..
