You wouldnt buy a very good car, which an audi is, because of image 
A Hyundai i20 is a good car. Would I buy one of them?
No.
I've had Audis...they are very well built etc...but assumiung the S3 was so good that I got over the image problem, then yes, I'd buy one.
But it's not.
It's quick, but the suspension has little feel, the steering even less and it's boring as hell to drive hard.
So would I buy an imperfect - but well built car - with an image problem?
No, I wouldn't.
