This was one of a series of A1 Grand Prix Series 'Presentation Cars' that may not be representative of the vehicles that actually raced. It appears that Amalgam only did this for the split 2007/2008 season and there is no mention of any 1:43 models on their website today.
The series ran four seasons, 2005/2006 to 2008/2009. It never fulfilled the objective of drawing F1 fans during the Northern Hemisphere Winter. Amalgam makes high quality models and these sold for twice the price of a Minichamps. In the secondary market, they are very inexpensive. They may be of interest as an early ride for some sportscar and Indycar names
