It's probably a mark off Top Gear's slight (OK, significant) car obsession that, when found out the plotline to Bionic Woman - in which a normal girl gets incredible strength and bionic powers after a dodgy operation - we immediately thought 'aftermarket tuning'.

It works, we think: more power, more speed, slightly shifty undercover operation? No? Anyhow, aftermarket analogy or not, Bionic Woman - starring Eastender Michelle Ryan - was a massive success both in the US and over here in the UK. And we're giving you the chance to win the entire series on DVD, along with a Nintendo Wii Fit for developing some bionic powers of your own.

One lucky winner will scoop the Wii Fit along with the entire Bionic Woman series on DVD, while two runners-up will each win a boxed set.
