Pah - amateurs.
I got...
2 chairs, 2 fleeces, 2 sleeping bags, some shirts, a pair of jeans, a towel and some forums stickers in the Roadster without touching any cubby holes or the boot
In the rest of the "space" - I got a 5 man tent, 4 litres of coke, a gazebo, a forum banner, a guilotene, more stickers, flyers, a weekends worth of food, 3 disposeable bbq's and a coupe boot spoiler.
Looking forward to trying to break this personal record at the next JAE or camping meet.
They are practical, you just need imagination.
PS - you even get a sticker with the roadster showing how to get one golf bag in the boot.
