I tell them I have a 2018 Bugatti Veyron, a 1988 Ferrari F40 and a 2016 Rolls Drophead Coupe. They hang up on me
I've used this same tactic, if I have time, I will waste theirs. Heck if a Bugatti Veyron oil change costs $20k, and tires which don't last very long at all cost around $40k, and some service needs might involve shipping the car off to France, maybe an extended warranty would help.
