All Z4's are more than welcome to attend. If someone is willing to organise then the Z4 Forum can also have a specific stand, otherwise parking is by decades so similar Z4's will be close together.
There is free on-site camping on the Friday night.
Display car ticket sales end on Wednesday 31 May.
The forecast is looking really good for next weekend, real top down weather. https://bmwcarclubgb.uk/sommerfest/
