The AX was arguably Citroen's first serious Supermini and was launched in 1987 with attendant hype, which included a trip along the Great Wall of China.
Though under the skin, many parts were shared with Peugeot - including all the engines - the car managed to quickly develop its own unique Parisian personality, dispelling the myth that budget cars had to be boring.
The model range has included 1.0-litre, 1.1 and 1.4-litre petrol engines as well as a 1.4-litre diesel (upgraded to 1.5-litres in May 1994). Of these, the diesels were particularly popular, mainly because independent tests consistently found them to be the most economical small cars it was possible to buy.
The budget 'hot hatch' GT models were - and are - also in demand, with the best made between 1991 and 1992, incorporating the facelift improvements. Rest to sixty in these non-catalysed cars takes just 9.2 seconds on the way to 108mph. Yet insurance is rated at an affordable group 9.
Later warmed-up variants (known as 'Fortes') gained catalytic converters but lost power as a result. The ultimate AX was the 100bhp fuel injected GTi, produced between 1991 and 1994. It sold poorly, however and suffered under group 11 insurance, so used examples are rare.
