Sales Promotion, Show Car Account, VIP, Special Prepared.
Those terms really all mean exactly the same thing.
My guess, is that the 80055 Account was the special request account that GM of Canada used to order "Special cars". They were possibly inspected for better quality, and likely had a better fit and finish about them. The paint may have been polished to a better shine. The engines were likely detailed for display.
These were the cars GM was going to use to put their best foot forward.
Used at races, auto shows, celebrity, and sporting events, ect....
The 80055 cars were specialy prepared AS show cars.
Everything about these cars was maybe to a higher standard.
