Nothing.
The Jetta is responsive, dependable, well built and fun to drive.
The cabin is quiet, the tiptronic shifter is a joy to use, and the stereo is not cluttered with a zillion buttons. It's very easy to navigate the controls.
The overhead night lighting is just as in the more expensive Audi, and the Leatherette seating is a nice touch for little money.
Gas mileage is great and value/performance factor is a whopping 10.
Leatherette...that is a fancy term for VINYL. And you paid EXTRA for it!!!
You speak of an awesome deal... so SHOW US THE MONEY! What was so awesome. Was the car 1/2 off? Free? VW credit gave you 0.9% and made the first 6 payments???
It sounds like you are just happy to have a new car with PVC seats...
"A disadvantage of plastic "leatherette" is that it is not porous and does not allow air to pass through it, thus sweat can accumulate if it is used for clothing, car seat coverings, etc. However, one of its primary advantages, especially in cars, is that it requires little maintenance in comparison to leather and does not crack or fade as easily."
Less maintenance and longer life? Leatherette seems OK by me.
