I'm not from Michigan, but that's the way I was reading it, too! I wasn't going to ask, so I'm glad volvo9 did and now I know.Don't feel bad.
Living in Michigan means being conditioned to seeing everything with MI in it. So you have MI Volvo dealers and MI pancake house.
It's gotten to the point people pronounce it as "my". so it's MY Volvo Dealer when pronounced.
And every time I see Model Year MY, I want to read it as my 2016 rather than Model Year.
