Traditionally, all new Morgans were taken for a test drive prior to dispatch from the factory. Obviously, this no longer seems to be the case!
My Roadster was, but you can't (legally) get above about 30mph, on the local roads, I think it's more of a 'bedding in' than full speed shakedown test (well, apart from the Aero8 write off)
Mainstream manufacturers have rolling roads, simulated Belgium cobble tracks and sealed wet leak test chambers...for a reason
