There were 6000 Y68 packages produced, and dealers were apparently allowed to put regional badging on these cars. In my area of the country, they were given "Edge" badging, in sticking with Oldsmobile's ~sharp~ imaging apparently. Other areas of the country had different names for these cars, I've been told.

Thanks to Harv!
