I'm relieved that it's not just me! I have a 1975 P plate 127 - no idea where, haven't seen the thing in ages - which not only has a cat flap where some preferred a hatch, but also has the frontal styling like that one in your thumbnail image. It's not actually that rotten, started out as a yellow example and was painted black in 1991 as the previous owner wasn't fond of yellow. Why she didn't buy a black car to start with I don't know.
The only thing I remember about the car was that when I bought it, there was an eighth (roughly, I didn't check the exact weight) in the ashtray along with a pack of papers and some very dry Old Holborn, all of which made the trip home much less horrible.
Actually, there are other things I remember; that little 903cc pushrod engine revved like a mad thing and gave the car a surprisingly good turn of speed, the handling was, erm, "interesting" but only because the rear spring had a break close to the middle so wasn't really doing that much, the heater was ferocious and the wipers didn't work unless the left indicator was switched on. But at least the brake calipers weren't seizing on
all the way home and the interior really was nice.
