European Cars vs. Japanese Cars??

One day, I overheard some mechanics chatting: "People who've driven European cars, when they go back to driving a CC or RAV4, some might feel the car body is a bit more shaky." After hearing that, I asked: "So, is Toyota not as good?" Mechanic: "No, it's just a different tuning." Me: "Then if I drive a European car first, can I never go back?" Mechanic: ...... Did I ask another dangerous question again? 😂
