Some avid car buffs know that the vintage MG was largely a 1923 Morris customized at Morris Garage using available parts. The rest is automotive history. Wikipedia recites the history of this now legendary garage:

The history of William Morris, the 1st Viscount Nuffield, is also compelling:

Given this very colorful history, "Morris Sons Garage" might be an interesting building -- and, a great layout conversation starter. In this regard, many of my "car buff" friends who view my layout actually spend more time examining and discussing the classic 50's and 60's era autos than the trains and rolling stock! A "Morris Sons Garage" would add to the fun.
There may be some licensing issues depending on how the design of the building and its contents is implemented. Using more generic autos may solve that issue -- as postwar Lionel likely knew.
...Perhaps some vintage, "Hagerty Insurance" ™ signage would add to the fun and nostalgia!
