I purchased the 2008 Jetta S a month ago. So far it has been a great car. I like the fact that the basic model looks practically the same inside and out. I opted for the "Titanium" package, which included the 17" wheels and rear spoiler, and it was definitely worth the price because the wheels really make the car. You would never know that it is a base model when seeing it drive by.
I love the iPod adapter. However, I don't understand why it is in the glove box. It would be much better somewhere on the dash or console. And also the optional 17" wheels, highly recommended to make your car an eye catcher.
I went with the black interior and my only complaint is that it is impossible to keep clean. I find myself constantly picking lint from the seats that won't come off with the vacuum. But, no biggie. It would also be nice to have the splash guards standard on the car. I put them on after one week.
