I got mine for silly money from a guy who was getting divorced - £8k!! Worth £12k private easily and £15k+ at a dealer all day. They're actually going up in value now, they have the modern(ish) performance and reliability of the 993 with the looks of the 3.2 and earlier cars. Targa is the least loved, cabrios and coupes fetch more. Never understood why, it was always the Targa I wanted if any as it does the job of both! Such a lightweight little car, 285bhp and sounds amazing... every time you put your foot down it's like being in a Classic Le Mans race! I reckon £15k would get you a mint manual coupe with 80-90k miles if you were in the right place/right time. There are only a few cars on 911uk, probably tons on Pistonheads. I have honestly never had a car tha gets so much positive attention - it looks like a Beetle really and the narrowbody C2 is as non-threatening as a sports car gets. Hippies love it!!
Long term, the Esprit and 964 might become a 360 Spyder... she doesn't know that yet though...
