2013 audi a4
So i went to go test drive the base model a4 with just the convenience package yesterday in order to see the difference between the vw jetta/passat. I was pretty disappointed. Now I've drove a quattro before and that's fun, but the base fwd no. The vw actually feels faster and more sporty. The only compliment I will give audi over vw is their seats are more comfortable. The seats in the vw are like rocks.
The other thing that was annoying is you have to get premium plus package in order to be able to put the back seats down. Why wouldn't that be standard? But honestly, I see no reason to spend the extra money over a vw to get a base audi.
