Say it like you really mean, Doc! And Tony, wouldn't the one advertised be a twin-carb version? MG 1100s and 1300s in the UK were twin carbed, except for automatics, as distinct from Austin and Morris 1100s.
For a while the 1100 in its various mostly-badge-engineered forms was the best-selling car in the UK. They handled well, were very spacious inside, particularly when you consider their overall dimensions, and on the narrow, congested roads of most UK towns and suburbia were fine. Motorway cruising was another matter, though!
They suffered mostly from dreadful build quality and rusted like mad. I remember buying a 1968 MG 1300 (for its engine only, to put in my wife's Mini) that had been rear-ended and written off. It was 3 years old, but already had significant rust penetration.
