Vroom, vroom................. 
Looks like a Martin.
I'm never one to complain about threads going a bit off topic, but I wonder if anyone clicked on the link in my initial post to see the "case" for the return of the British GP to Aintree.
Acknowledging tobylvp's copywright, here is the gist:
F1 racing was stopped there because the course was changing owners and the future not certain. The track is largely still there and still used.
The top-class spectator facilities now far outstrip any British motor course. Liverpool is far superior than Donnington or Silverstone for transport access and hotels being a World Heritage Site tourist city in most of the city centre. Cruise liners regularly visit the city during the summer months. Liners could acts as hotels for F1 races if need be. Cars will not be allowed near Donnington and access is only via the local small rail station. Car parking is no problem at Aintree.
Aintree hosts the world biggest horse race each year catering for massive crowds – they know how to handle it. The course has its own rapid-transit Merseyrail tube station with direct connection to mainline Lime St station which is two hours from London by Virgin trains. There are two motorways adjacent to the course and two into the city. An international airport is near with frequent flights to all major European cities, and also a smaller airport near for the event & owners helicopters.
This is a clear lost opportunity for Liverpool, Britain and F1. The city has image world-wide, especially sporting linked. The city hosts huge football games (semi-final of a world cup was staged in the city) and international golf events at Hoylake and Birkdale (many Golf open tournaments of all descriptions). Two large stadia are to be built in the city. Large sporting events is something common to the city. Upgrading the track and install pits is something that would take little or time money to get to full F1 standards and British F1 history rekindled.
Why isn’t the city of Liverpool council, Sefton Council, the Jockey Club and Ecclestones talking. The course could be ready in months.
Discuss....

Obviously
Tobylvp has very little grasp of reality. His closing comment "The course could be ready in months." is a classic example of someone who doesn't know what they are talking about. The core business of Aintree Racecourse is horse racing. Anything that could adversely affect this core business is not going to be supported. As I said earlier there are various elements on the track that will require realignment and that would mean pinching slices of land off the horse race track - this will never happen.
Having said that the Club Circuit is a totally different kettle of fish. There the track is completely as was. All it needs is .....
1) resurfacing,
2) Armco barriers to protect the cars from the Grand National jumps and which can be easily dismantled & stored,
3) Moveable barriers to be positioned so as to block off the gaps in the safety banking,
4) crowd control barriers (assuming that spectators will be admitted),
5) additional tarmac areas for the paddock,
6) a race control building,
7) a pit lane,
8) removal of large sections of the perimeter chainlink fencing to be replaced with taller fencing to stop unauthorised access and to be faced with Armco,
9) additional toilet facilities for both competitors and spectators,
and finally
10) planning permission.
I would guesstimate that the costs for this would be in the millions. You would only get 12 days per annum at the most (6 each for bikes and cars) plus you might get some midweek testing.
All in all not exactly a viable financial prospect.
