Top 20: Fastest disappearing cars from UK roads

We've been crunching data again to come up with the definitive list of cars that are most rapidly disappearing from our roads - and looking at the 20 cars featured, it's a case of natural selection working in our favour.

What we did was gather the numbers of all types of cars on the road between the end of 2007 and 2011. Then, we calculated the percentage remaining for all cars at the end of the five-year period, with the intention of working out which cars are disappearing the quickest, and how many are left. If you're a fan of unloved 1990s family cars, the read 'em and weep - for they are going fast. If you want one, be quick before they're all gone!

Sao Penza. Population in 2007: 13, population in 2011: 3,
for 23.08% of '07 cars remaining

The Sao Penza a South African built 323 sold in the UK for a couple of years, as a bargain alternative to the Japanese-built Mazda equivalent. It hit the market at the same time as the Kia Pride, which was also a badge-engineered Mazda - this time, a 121. It's interesting to compare the fortunes of the two companies...

With three left, and little likelihood of finding any enthusiastic owners near zero, will the Sao Penza be rendered extinct before too much longer?
