Any Wycombe PHers?

[Dr Jekyll]

Just on the SW outskirts, after leaving the M40 at jct 4 and turning left at the Turnpike roundabout towards Booker airfield, there is a large detached house on the right which always had about a dozen 'prestige' cars in the front yard. Jags, Range Rovers, serious BMWs etc.

Anyone know what it is? Dealer? Car hire? Rich family?
