It's been open for a fair old while....
If you watched ITV's coverage of the race last weekend their "meet the team" was McLaren and they had a tour around it.
They do produce the SLR their (apart from the engines) as well as the F1 cars. I personally dont think its a waste of money, it goes perfectly with the McLaren and Ron Dennis' ethos. Its not as if they're spending their R&D money on it and which team has been the closest to ferrari this year, in the latter half of the season anyway, and if it wasnt for MB's engine failures they could well be a lot further up the table
