OK, if this doesn't give it away then you're clearly not Midlanders...either that or you're far better at travelling the world than this small corner of the UK!
You've bracketed all around it but no-one's got within ~20 miles.
Easton Neston is the closest but I've given a very big hint if someone uses google maps... ...especially if I add we could hear the repeated background roar of V12s testing a couple of fields away...
