just tell them that the engine used in the prius is a joke compared to honda's

and vice versa with the hybrid system. also slam in their face that you saved a couple thousand compared to what they spent, making your fuel savings "more real". And tell them you didn't have to wait **** for your car, while they went heels over toes to get their and had to pay more than MSRP price.

oh and tell them your car corners better too haha.

i got around 20 km a liter when i drove a civic 5 spd using advanced hypermiler techniques
and now I drive a salvage nwh20 prius that gets almost to 25 km/l with 192,000 km to date.
