Just done my 19th Geneva Motor Show, and this one was like no other car expo I've attended in Switzerland, or anywhere else. What made it so different? The fact that one company - Citroen - simultaneously launched a new entry-level city car for cash-strapped kids and a top-of-the-line, £30,000-plus executive cruiser. These models are not cynical concepts created by vain Paris-based designers to show how talented they are. They will be on sale in Britain in a matter of months.
