Don't know if i can explain this fully but the door top / rear side window shape on a lot of modern 2door hatchbacks..
off the top of my head i know this feature is on the 2door focus, the corsa and the saxo, probably many others as well..
what i'm talking about is that because the top of the glass in the door is the same height as the glass in the side window behind it, you end up with a really ugly L shaped panel gap from the door frame going higher than the glass..
if anyone has a side on shot of a focus or a corsa they'll see what i mean i hope.
On the Citroen C2, the way they've sloped the waistline on the side windows and the doors up meaning that there's no clear waist line on the car
Citroen again, the C3 "Pluriel".. all of it.. it's ugly from every angle and totally pointless as a concept (imho) it does make me laugh however that Citroen are enthusiastically publicising that they've made a car that structural bits fall off of.. they've been trying to play that down for years
Jaguar, deciding to provide diesel engine options for any of their cars.. i'd argue that this is a style point because jaguars are supposed to be suave, sophisticated, lean and catlike.. no matter how good the diesel engine they're using is it's not a cat.. the only animal it seems like is a smoking beagle.
Ford Sierra, the whole car because it's new aerodynamic design is what killed off all creative thought in car design.
Honda Civic.. the gearstick coming out of the dashboard affair.. damn that's ugly.
Datsun.. sorry i mean Lexus... creating those godawful rear light clusters is strike one, seemingly being responsible for kickstarting the craze of gold plating the badges on your car is strike two.
Rover 75, bringing back imitation chrome door handles that stick out from the bodywork.. for crying out loud it's not the 1950's anymore.. that car could have been a sleek, well proportioned budget jaguar, Rover made it into a mock tudor mobile punchline.
Any and all manufacturers, using fake wood or metal trim on interiors.. if you want wood in there, go and buy some trees dammit..
Nissan, canning the r34 skyline and releasing the new one.. just plain ugly.
Vauxhall, binning the Manta in the late 80's then releasing the Calibra as a fwd car based on a cavalier
Vauxhall, restyling the Monaro to have those stupid nostrils, then canning the car as no-one wanted it.. muppets
