^^What Mokeyhanger said!!
And as for comfort, its absolutely a priority to me as a big business user. I'm on my second GTD in 4 years and I was happy enough to not think twice about ordering the same car.
I have no idea who told you that they are uncomfortable, I'd rank it as one of the most comfortable cars I've had in 30+ years... and in that time I've probably had 20 different cars.
Maybe if the person talking about it had a particularly large bottom? If so, don't buy anything sporty unless you can afford a Rangerover sport or something. Get something with big wide seats.... not that a performance golf has racing buckets either!
