Some of us are crazy about Porsche, and especially 911s. We were curious to see whether the price of 911s on average is increasing or not in the second-hand market so we decided to find out.
We started by scraping the classifieds of Europe’s largest second-hand market, autoscout24. However, as any Porsche fanatic knows: not all 911s are created equal. Adding them all up there are multiple generations; early 911s, 930, 964, 993, 996, 997, 991, and the 992. Then there are variants; C2, C2s, C4, C4s, Turbo, GTS, GT2, GT3 – it can be hard to make sense of them all. So we take the supply of all of those models, and we distribute them by their respective types, weigh each model, add a modifier for the variant, and we have ourselves a price (of some sorts) for each car. Now we find an average, and we look at the delta and plot it. We started our index today at the (not so) arbitrary number – you guessed it – “911”.
Now you can show your wife this chart when you explain why there’s a Porsche in your driveway, and why the kids are going to be paying their own way through college.
