Hi Conor
here is the package in as much as what it costs to produce an automobile the french produce cars in mostly three factories Citroen, peugeot, and renault all three have similar body shapes which means most of the body parts come from the same steel pressing shop.
they have different markets the Citroen tend to be the most advanced ideas such as electric steering and pneumatic brakes, the renault tend to be the most basic and Peugeot do have the best diesel engines.
so what is the issue well they don't stay with one model very long before they come out with a new one. so spares tend to be a problem sometimes with body panels.
they the idea is to build a car which has a life expectancy of a maximum of 10 years and they need to be scrapped and recycled so when compared to some makes they are cheaper.
So as we english have always had issues with the french in the past 500 years some just keep this hatred up. which is what some of what you hear when something french is mentioned.
Not true but some just can't let it go. hence the issue over concorde. if they had bothered to clean up the runway concorde would still be flying the fact that this was an inherent problem waiting to happen some feel it had nothing to do with it.
so yes they are cheap cars made for a price and have a life expectancy so yes some have issue more out of national pride than fact.
the Ford or the hyundai or kia are no better really. so you pays your money and you make a choice.
