Top Gear presents a Summer Special. James May and Richard Hammond look at the best new convertibles. Clarkson puts the Nissan 350Z through its paces, Top Gear's own James May nominates the Citroen DS as his 'Greatest Car', and supermodel Jodie Kidd is our 'Star in a Reasonably Priced Car'. Plus Top Gear finds the driving 'Master of the Universe' when a Dalek, a Klingon, a Cyberman, Ming the Merciless, Doctor Who (Colin Baker) and Darth Vader go head-to-head on the track.

The team has trouble deciding if the TVR 350C or the Noble is the best shed-built supercar in the UK. Jeremy tests the new Phaeton, Volkswagen's first high-end luxury saloon. James May looks at the new Cadillac 16. Five disabled drivers compete to see which is the fastest. And we find out who is the series' fastest celebrity guest star.
