What makes you think that the list from
What Car Magazine, which report the Mercedes C-Class as top stolen car, is more reliable than the ones reported by the likes of, for example
the Guardian, which back in 2016 reported the S3 as the top stolen car?
Well you have to look at the data source to find out. Annoyingly (and perhaps unsurprisingly...) most places don't ever source the original study/data, but after a bit of digging I found one article that had the same list as the What Car list, and said it came from data from a Tracking company called TRACKER.
Here is there original list which presumably is where all the other sources got the information from.
The TRACKER article itself is extremely vague about what the data actually is. Just relies on you to trust them that it's all reliable data and that they've analysed it appropriately. Call me skeptical, but I did a bit more digging and found their
original release back in 2016. You can see from the numbers, it's basically just the number of stolen and recovered based on the companies data....the numbers themselves, well here they are:
1. BMW X5 - 30 stolen and recovered
2. RR Sport - 26 stolen and recovered
3. ......
Well I don't think I have to go down the whole list to point out the painfully obvious flaw in this data...the number one stolen car according to them was the X5, because 30 were stolen in 2016....30.....out of a total of
80,000 vehicle thefts recorded that year...hardly a representative sample! I would not even consider this list as remotely reliable or informative, since it represents a ridiculously small proportion of the total number of cars. I would guess that of the total number of cars at risk of being stolen, the number that have not only a tracker, but specifically a tracker from this company TRACKER, is ridiculously small...Put another way, it's meaningless...
(As an aside, this same list was reported in numerous media outlets, including
The Express and
The Sun...So whether it's reported in the media or not is not in itself and indicator of it's reliability)
So what about the list from the Guardian that did the rounds in 2016? The one that had the S3 as the most stolen car? Well the article gives you the source and it's from the
National Vehicle Crime Intelligence Service. Likely to be a much more reliable source than a Tracker company who only has data on cars that are fitted with their tracker....Annoyingly I can't find the original source data (if anyone can let me know), but the fact that the figures are reported as a incidence rate per 1,000 (much more appropriate way to analyse this data as it takes into account the fact that there may be more of certain cars on the roads), and that it comes from a national body who specifically police vehicle related crime in the UK, suggests to me that it is much more likely to be a reliable data source.
TL;DR - The estimate that the S3 is probably a far more reliable estimate than that from the What Car, that was based on very unreliable data from a TRACKER company.
Top tip - Always check the source!
