I went on Thursday, didn't bother going back today. Some big names were missing from the show this year, notably Prodrive. The trade hall was a lot smaller than it has been in previous years, from what people were saying it seems that they didn't offer stands at reduced rates to try and fill it at the last minute like they did last year. The main public stands were rather pitiful with none of the F1 teams and very few other major teams having their usual large promotional stands. The F1 and WRC cars were parked up like they were on a parking lot.
Sadly I think Autosport has shot itself in the foot charging too much for stands I can't see many members of the public coming back next year and the trade shows integrity must be hurt by some of the big engineering companies choosing not to have stands, even on the trade days.
