    How accurate is the information? Especially model types and the quantity of testing?

    Two cars of mine tested in 2016 dont show up in that data?

    This dashboard displays a filtered version of the original data set, (NCT tests conducted in 2016, available from http://www.rsa.ie/) showing the 20 most popular makes of vehicle in the dataset, and for each of these, the models with at least 1000 tests carried out in 2016. The dataset covers the results of first tests only, and does not take into account mileage, maintenance or service history, and therefore may not directly evaluate vehicle quality.

    The Nissan Puke is helped along a good bit by only having been in production since 2010 so it's quite meaningless unless you're only comparing cars of the same year. Also if cars are failing for consumable items like tyres and bulbs that's more a reflection on the owners of those cars

    It wouls be nice to have an equivalent of http://howmanyleft.co.uk but you'll need contacts in the secret car registration inner circle and a hefty wad of cash to glean that info.

    But that's still a good indicator of reliability and passability in future. A neglected car will fail more often...

    Yes, unfortunately it seems the pass rates are more or less directly proportional to the age profile of the model. Look at the Honda Civic or Toyota Corolla/Avensis, for example: They have unusually low pass rates despite being current models, but the majority of the cars doing the test are 2008 or older. If you search only 2009-2016 cars you get significantly different results.

    Agreed. Older cars are indeed more likely to fail - that's why we put the age selector slider at the top!

    However, we think that if you're looking to buy a used car, this will be a handy tool for checking out cars before you go see them - to see how reliable the model (of that age) is, and to understand what it's most likely to fail on.

    As for the 270k tests that we excluded, we had to cut it down otherwise it'd have been quite unwieldy. Also, there's a lot of bad data in there, where the model has just been input wrong (or at least inconsistently). However if you're interested in a car that's not on the list, you can download the source data from the RSA here http://www.rsa.ie/Documents/NCT/Make%20Model%20Data%202016.csv and filter / search the makes and models that interest you.

    The independent have done an article on this but they made a mess out of it. Despite mentioning that some models have been around far longer than others they still draw the headline grabbing conclusions they wanted.

    Bloody media today.

    The Fiat Panda seems to be doing very well. And that was last produced in 2012.

    The Pandas I've seen are usually fairly clean and looked after. I've noticed that with certain models, they tend to be looked after more than others.

    Remember fondly my sister's old (model) Panda :) Surprised (not sure why) to see them being so reliable.

    Incidentally, the lad who created the dashboard gave me a look at the data that we've had to exclude from the report. Seems lots of cars tested last year were had 'other' as either their make or model, and some were completely misclassified. For example the MX5 was represented in about 5 different ways, and no logical split. So sorry about that, but some of the data's of really low quality.

    You can look at the source data on RSA.ie if you fancy digging into it.

    Hi all,

    We've updated the NCT dashboard with the 2017 test results - here: https://public.tableau.com/profile/idiro.analytics#!/vizhome/NCT2017Top20Makes/NCT2017-20MostPopularMakes

    And also, we created a simple utility to allow you to look up the detailed NCT results for any make / model / year - you'll find it at https://idiro.com/NCTchecker.

    Detailed instructions for both are here: http://idiro.com/2018/08/will-my-car-pass-the-nct/

    Feedback welcome.

    why would a 2016 or 2017 car show up
    surely youngest would be 2013 for the 2017 results year ( 4 years from new ? )

    Bad data input I'm guessing...

    I would hope they don't mix commercial with domestic. That would make a farce of the data.

    I mean if you have a data set, taxi's or hackneys etc, or work vans, shouldn't be mixed with private use only vehicles as much as possible. As it would distort the data and any analysis of it. You should be able to seperate them.

    Same with years age of vehicle. The results should be averaged per age of the vehicle. Not mixed across different ages.

    It's a good question. We spotted that and we guess that you can get a car of any age tested, but why you would is a different question. I'll see if we can find out from the RSA (it may take a while).

    UK imports don't need an NCT until they're 4 years old either. And the MOT is now transferable.

    If you buy a brand new taxi with 0km it’s must still be tested before it gets a licence.
