Porsche has been making the 911 for ten thousand years now, so they are virtually flawless in terms of quality and build. A point proven by a recent TÜV report naming the car the least defective used car you can buy.

According to the German Technical Inspection Agency’s report Porsche 911s have shown the fewest defects among all vehicles in its age group. They studied seven, nine and eleven years old vehicles and in each category it was the 911 showing the best results.

That is hardly surprising when you get to know how Porsche make their cars and how well they are engineered. This video of the new 991’s development is a good example.

And it’s not just the 911, all Porsches are built with utter brilliance. The same as the year before, in each of the general technical inspections, the TÜV inspectors found the least grounds for complaint. Overall, the 911, Boxster and Cayman models occupied five of the ten best rankings across all age groups, which is once again impressive proof of the Zuffenhausen sports cars’ long term quality and ability to hold their value.

The Autobild TÜV Report is based on data from approximately eight million general technical inspections between July 2010 and June 2011. So if you want a trouble-free used car, get a Porsche.
