It looks nice (best colour imho), but plenty of manuals to choose from right now. I'd tend to not pay over 10k for one, so this seems about right. What brand are the wheels? See what service history it has and if the usual culprits have been addressed (water pump, thermostat, valve cover gasket, oil filter housing gasket, sump gasket, coils, plugs, etc, etc.)
This claim sounds very dubious if my memory serves me...

Check the tyres aren't rock hard rubbish.
