Quoted from kvan99:
BMW sucks...Owned one...just once. Audis are supposedly real good now, but I just never liked their designs. I've had 3 Porsches, one after another, I'll keep buying them till they disappoint me. It hasn't happened in 12 years though.
I have friends who are happy with BMW. I have friends who are happy with Audi. I have friends who are happy with Porsche. And more. And I have friends who diss any one of them too. Good experiences and bad experiences will happen with any one of those manufacturers, as they also do with the domestics.
The asian cars offer a lot a great build, quality, and value, though dollar for dollar the public finds they tend to have a more bland character from the equivalent domestic or german cars. In the end it depends on personal preference and values. I see merit in all the options out there and have owned much of the spectrum, happily so.
