Theres a super car show happening at Wilton house in Salisbury next Sunday (14th August). There are loads of expensive, rare, and downright amazing cars at this show. The cars turn up at noon so you can see and hear them drive in. Then its a static show until 4pm, or at least it was last year.
A very good day in my opinion with the chance to see a veyron, mclarens, ferraris etc etc.
I'll be going, not sure if I'll be taking the mini or the BMW, I'll see what the weathers doing and decide on the day.
