Breathtaking driving experience, one of few cars that's good on both road and race-track, quality, history, design, lightness, performance
The ride's a bit shabby, comfort is poor, cramped cabin
If you're tempted by the pros, the cons won't matter; if you're put off by the cons, the pros won't - we're in the first of those camps
On most models, running costs are surprisingly affordable. The big problem is affording a new one in the first place - you can now spend upwards of £40,000 on one. But, insurance is reasonable (you can get Sevens on specialist policies costing a couple of hundred pounds a year), while servicing isn't overly expensive thanks to a number of honest specialists and most Sevens' simple mechanicals. Best of all, though, most Caterhams depreciate very slowly. The small engine and light-weight means that fuel economy's reasonable, too.
