That is a really nicely specced example in great condition kmpowell, I am sure that will sell very quickly. 
Each to their own, but I am not about to sell my CS for a 7.5PP. I speak as an ex mk7 PP owner and have driven 7.5 GtiPP & R on a few occasions.
Maybe short term wallet comes into it, but In 2-5 years time which car will be worth more? 
The good thing about a golf is if you want to see what way the prices will
eventually go, look to it's predecessors.
Mk2 G60/Rallye, Mk4 R32, Mk5 Edition 30/R32 all highly praised cars at the time of release then dropped way down in price, (£1,600 in the case of the Mk2 Rallye now selling at £35K+). Although I wouldn't buy a mk7 as an investment unless you plan on keeping it 20+ years and not driving it

If I could have found a Clubsport (that wasn't white...) I'd have got one over my 7.5PP but I'd have had to add 20/30k miles and £2-3k.
