I'm in the market for a new or used RS5. I was going to go the new route but to save $$$ I am thinking about a used 2013/2014 RS5 and using the savings for mods. I kinda have my heart set on Suzuka Grey.. A Titanium package and or a Black optics package would be preferable also. I have found a few low mileage (under 10,000) certified preowned units, some with those packages some without. What should I expect to pay for a low mileage RS5? What is the treadlife of the OEM tires? As far as new is concerned they don't seem to be moving off of dealers lots lately. How much room is there for negotiation on a new one?
