Vauxhall, because I've been left stranded twice by them and when ever I've driven one I've hated it to the point of mental illness
Mercedes, they make fast ones, but they're boring too
BMW, because if you dont have a warranty or a BMW qualification you're up the creek how do they sell so many 1.6's and 118d's if they are so unreliable
Now the wierd one, Honda, as much as I used to love them and I've owned a fair few Honda's I cant stand the fact that they've gone from making amazing cars to being the most boring manufacturer on earth, the CRZ, the one car that could have been awesome in recent years was more than disapointing and it doesnt look like they've finished boring the pants of everyone yet with more boring tweets and facebook updates than you could ever be arsed to read the mind numbing boredom continues with nothing but a sniff of a rumour that might, maybe, possibly have something to do with a 1.6 Turbo. Even the Koreans are ahead of Honda. Bah.
