This 2 hour film is basically a review of the years 1991 - 2002 inclusively of BTCC. And while it skips through the action and misses some out completely, it is a fantastic summary of the best of BTCC action - i.e. battling and crashing.
The commentary ranges from Murray Walker, through Charlie Cox up to Ben Edwards and is exciting. Each year is given 10 minutes approx of the best of the best.
Basically if you want good in depth coverage of BTCC's history, buy the individual review videos - but if you want the best flavour of the action buy this action packed DVD.
