As a previous thread has touched upon some cars both old and new are things of absolute beauty, others can be rather nice and practical, whilst some unfortunates are just so damn "pug ugly" one can't help but feel they were designed by someone with a grievance against the company or they had exceeded the dosage of their medication.
The Leyland P76 comes to mind, as does that cube like compact wagon thingy that even by using cute Pandas in the Ads couldn't sell one, it was such a great success that I can't even remember the make.
Maybe we could have categories based on production dates or just omit the "good" and just stick with the "bad and the UGLY"
So . . . . . irrespective of date of manufacture IMHO a possible nominee for the "Ugliest" car ever produced that I have seen goes to the 1950 Austin A90 Atlantic Convertible, a super sleek under powered, three eyed poxy little mutant of motoring.
This one was photographed at Latrobe Tasmania at an Austin Car Club get together.
I have a couple more in mind
