There is several immaculate Audi B6 2004+ S4's in my area for $13,000-15,000 I think they are more along the lines of a C5 non z06 in price.
With that said a C5 is quite the bargain, id take a C5 over a Z06 and then do intake, exhaust, cam and have alot more power then a Z06 and not to mention Targa top for the win.
bolt ons + cam you are easily 380-415whp and i dont think you can get a Z06 with targa plus you will still be cheaper then a z06. a friend of mine picked up a bone stock 01 C5 6spd for $13,500 and runs 12.80@111mph. hate to see what he will run with some mods...
