- you have good taste in cars
As for the car you have spooted, yes it is a UK GT car and good value IF the mileage is right. Check the service history carefuly - hopefully its got a FNSH and the bills to verify.
Its got the standard Bose stereo fitted to the UK cars. and Brembos are standard on all UK supplied cars. Standard alloy wheels - all look in good condition but check for re-furb work as they almost look too good, but if the mileage is right then should be OK. Check tyre wear - might help reveal mileage (or abuse). Take a bit of time using the search button on here to check for the known issues.
Get a HPI check done at the very least and if you can, ring the last the owner to verify the authenticity. The dealer might want to do a deal as the colour is not always a favourite (OK in my book and many others on here) and at this time of the year its a great time to haggle
Good luck
