We got waved in to the 'nice car' car park last year and then wandered in for free. They even gave us a programme for nothing. It's back to a one day event this year so will be very busy, but it's well worth a visit.
The interior may pass for a 7K car but unfortunately the paintwork gives it away as the 79K car that it is, it's covered in stone chips. It does get well used though.
The cracked bumper was a case of me thinking I knew better than the parking sensors!!
