However some manufacturers have put a great deal of thought into their displays. Here's our top 3.
Number 1 - Volvo
It's not the biggest but it's certainly the most creative and reflects the ethos and background of the company the most. Aside from the Swedish wooden building and ice blocks they've an artist creating a Volvo logo out of a giant block of ice, they're giving away snow cones, and you can vote for what song they play on the sound system via twitter. Oh, and they have free wifi.
Number 2 - Ford
Ford have created a massive lattice-steel structure that looks like a huge multi-storey parking lot. That might sound a bit industrial but it's a pretty stylish effort which showcases the cars well. And if you visit the stand be sure to pick up a free ice lolly. Ford have missed a trick by not branding them. Everyone in the vicinity has a Ford ice lolly!
Number 3 - Land Rover
Land Rover has taken a spot north of the main cluster of manufacturers. They've also taken a lot more room than the rest and have a large decked area with all their latest models (Range Rover Sport included), an off-road area, radio controlled Defenders on a miniature off-road course, and the usual steel and glass building. Jangle your Land Rover key and you'll be given access to an exclusive area where free drinks are served away from the hoi polloi. We did, it was splendid.
