Well ... there are lots of people online who are more than willing to expound upon the Allegro, although not always about its virtues, such as they may or may not be.
But there are a few who defend it, and in its own peculiar way it has become a bit of collector's item. In comparison to earlier models, relatively few of them sold. (Part of my point above.)
It was not a model that made it to Canada, sadly or mercifully as the case may be.
Depending upon the year of the vehicle and the angle from which it is viewed, the styling isn't quite as horrific in appearance as it once may have seemed. It can look slightly Alfa Romeo-ish.
And then there was the Vanden Plas version. Unbounded Luxury!
But the era was not the proudest for Leyland. UK-made cars developed a notoriety during this time. A friend had a TR6, faithfully and regularly dealer serviced, garage kept; it was at the dealership for warranty service more often that it was on the road in its first year or so, and it was plagued with rust. XJ6s, despite their gorgeous styling, could be horrifically unreliable, as some acquaintances were to discover.
A girlfriend once had an Austin Marina when she was a university student. Her lovely little cherry red VW Beetle with its sun roof had been destroyed in a traffic accident, and her father bought her the Marina. The colour scheme was purple and orange, extremely ugly. The car was awkward to drive. It was unreliable. She was greatly relieved when some teenage joy riders stole the car and damaged it so badly that it could not be repaired. They seemed to have ripped all the doors off by leaving them open and then backing them into telephone poles repeatedly at some speed. They seem to have fried the transmission, perhaps in the process of the door jobs. They also took box cutters to the ugly orange upholstery. The ugliness of the car seemed to have provoked a fury of indignation.
