Fault marque patterns - motorprop
Looking at the technical section, seems the threads follow a pattern on reported vehicle faults ; Renault, Citroens , Vauxhall , Ford and VW feature in descending order . A kind of democratic JD Powers survey ??


Very few mentions of Honda, Toyota and Lexus in comparison
Fault marque patterns - Screwloose

Fairly typical; but also a feature of search engines. "Birds of a feather..." etc.
