Richard Hammond celebrates the 40th birthday of the iconic Ferrari Daytona by taking one back to its spiritual home on the Italian Riviera before attempting to beat James May and a multi-million pound power boat in a race from Portofino to St Tropez. Meanwhile, back in the UK Jeremy Clarkson is out on the test track testing the new BMW M3 saloon against a young pretender from Japan, the Lexus IS-F. Top Gear also tackles a political hot potato as Richard attempts to find the best sort of bus for British city streets by getting together everything from a hopper to a bendy bus and then having a race with them. Plus, Grand Designs presenter Kevin McCloud is the Star in a Reasonably Priced Car.
