The biggest and most comprehensive analysis of MoT results ever has revealed the success and failure rates of virtually every car on sale in the UK.
However, it's not just the manufacturer of your car that determines how likely it is to get through its MoT - where you live has an effect, too.
Motoring consumer website honestjohn.co.uk has obtained over 24,000,000 MoT records from the Vehicle Operator and Services Agency (VOSA), going all the way back to 1980.
It has painstakingly analysed them to find out which cars have the best and worst pass rates, breaking them down by make, model, year of registration, and even postcode. You can find all the results here.
Looking at more recent MoT test results, it's perhaps no surprise that the manufacturer with the worst pass rate for cars registered in 2008 is French company Renault.
In fact, French cars resoundingly live up to their stereotype, taking three of the top five spots for most failed first MoT tests.
Almost three in ten Renault Méganes and Citroen C4s failed their first MOT - three times the number of failures notched up by the best performing car, the Suzuki Splash.
The graphic below has more details:
Of all the cars registered in the UK in 2008, one in five of them failed their first MoT - that's 352,000. Almost half of those were because of lighting and signaling failure, while just under a third were for issues with the tyres.
While it's perhaps not surprising that France fared badly, that MINI, Volvo and Mitsubishi - all manufacturers with anecdotally solid reliability reputations - are in the bottom ten is a shock; more 2008 model MINIs failed their first MoT than Citroens or Peugeots.
At the opposite end of the MoT spectrum, Lexus once again sits at the top of the tree - the Japanese luxury car company seems to top every reliability and customer satisfaction survey there is.
Dan Harrison of Honest John said: "Hard-pressed families can take this information and use it to ensure that they're not failing a MoT on something that can be easily fixed beforehand.
"Many failure items are down to the owner, rather than inherent fault with the car. Families using the data that comes from the 24.5 million records will be better prepared for their MoTs and be able to keep better control over the cost of motoring.
"This is information that has been kept from car owners for many years - VOSA even fought to keep it out of public view."
