I'd buy this from Duncan at Automotive Unlimited for £8500, Stage I it and pocket the rest of the cash
J plate, done 48,000 miles, totally standard bar a stainless.
Drive it for a year or two, keep it mint and get 90% of your money back when you sell it.
All the cars you have listed above will depreciate but a nice cossie will always keep its money and with a specialist insurer then insurance can be had for sensible money.
Oh and you get all the meets and show culture that comes with having a cossie...
