What do you say?

[Innuendo]

Chassis for us and Ch-as-ee for the yanks.

I think you'll find our Victorian's like to say Chas-ee here in Australia. For me it's always been Chassis = Shas-ee

My favourite yankie term is Bondo watched to much Chip Foose
Instead of bog

Yeah, Bondo is a brand like Hoover is to a vacuum cleaner
