Having had time to ponder, I was expecting something like Gaydon which it wasn't. Somone has rightly pointed out that Gaydon is run by AutoItalia and is a much more high profile event. I would perhaps describe the Beaulieu event as more like an overgrown italian night at The Ace but with the museum thrown in. There is nothing wrong with that so long as you know what you are going to. Brian and I passed up going to the excellent classic car day at The Shuttleworth Collection to go to Beaulieu which I must acknowlege exacerbated our feelings of deflation. So I think our disappointment could be taken more as a reflection of our expectations than a reflection on the event.
So next year, if you are within a day trip of Beaulieu I would say take a picnic, go along and swell the numbers. As with so much in our hobby, it is what you make it.
