For me it was $3000 for a bunch of stuff I didn't need or wanted that just added weight to the car.
The Interlagos cloth seats are a trademark throwback que and part of the car's character.
Aside from exotics that use leather for luxury purpose, cloth is better for performance driving as you will see in any aftermarket sport or racing seat.
The GTI's cloth in particular has a bit of ribbing that actually prevents you fro sliding forward on the brakes!
That being said, the leather seats have more agressive bolsters which are better for cornering. I'm a big guy though 6'1" and will never be under 210-220lbs. and I found the extra bolsters of the leather to be to intrusive for regular driving. I also wasn't a fan of the quality of the leather for the money, and not big on grey leather either.
Heated seats/washer nozzles? I live in Southern California. I'm half Finnish. I don't get cold here...ever. Try Helsinki in February.
Sunroof. My last two cars had sunroofs. I rarely, if ever used them. Most people don't - just look around you will usually find them closed most of the time. As a stand alone option it's like $1000. $1000 for a hole in the roof that will be closed most of the time, reduces rigidity and adds a good deal of weight at the highest point of the car.
Premium Audio. Just an amp upgrade to the factory system, and used to be available as a stand alone option. Oddly enough, even though my car is a "Package 0" or base model car with no options whatsoever, I do in fact of the amp underneat my passenger seat. I found that to odd, and while I certainly wouldn't have paid for it, I'm not complaining either!
So that's my reason why I didn't get the Autobahn package.
