I actually find the car show personal exchanges that attempt to discuss the errors of my cars an open challenge to humorously insult the other person.
For example, if the show is not very rural or all Mopar, I get a number of folks (all ages) that look at my ‘53 Dodge truck, asking me “Why didn’t you put a SBC or an LS in it?”
My typical responses are “It gets plenty of traction without all that weight laying in the back. Or, “The bed wood is new and the bed paint is great. Why would I want to have an SBC or an LS rolling around in the back?”
Always gets laughs and my critic moves on.
