What the Midget and classic Mini share is a small footprint along with incredible handling by the standards of the day. and arguably even now. Compromised only by limited power, downhill on the bends you won't get away from either in much faster options. We've had a number of both, so experienced this first hand. The MGB is more practical, but nowhere near as agile as the Midget as standard. Of course now you can get fancy suspension and Duratec engines. A Midget with a Duratec would be quite a weapon, but they are usually overlooked, because the MGB appears a more complete package.
I was in MGB's when the cutting edge drivers were in Escorts. I didn't get it then, and I don't now. I had one, a Mk2 1600 Ghia with bells and whistles, and signal orange. It was quite average on the road, and I never had another. A lad from a wealthy family turned up at the pub in a brand new TR6, yellow with hardtop. I envied that. His plate was PEN 30. Not so bothered about that. I should have got a TR6 but never did.
