I am really trying to decide on my first Audi. Both are CPO autos. One hand there is a 2011 A4 30k miles Prem+ Nav/Sport. However it has had the Crankshaft pulley/balancer replaced and the ignition coil 2x. On the other hand a 2013 A4 Prem+ No extras 15k miles.

I really want the tighter steering feel but is it worth the replacement of those parts even if its CPO? Also, would getting the 13 and adding STasis suspension and wheels or s4 wheels be an option? As you can prob tell I like to sport look,but don't want to live at the dealership.

I really would like to hear your experiences and opinions.
