“ Porsches and Audis had insane repair costs, compared to eg similarly sized Volkswagens”
It’s a known thing that those brands share parts between models, but the price will be substantially different if you buy the “Porsche” part vs the (identical) “VW” part. The price discrepancies don’t necessarily indicate they Audi/Porsche are less reliable.

No but once you express reliability not as "chance of breakage" but "repair cost", which IMO is the key metric for someone considering a used car, then it does. Especially when you also factor in the behavior of the average Porsche driver on the road, which means more wear and tear.
