I picked my 2000 LS-8 Sport for $10500. It had 100,000 miles but a 3 month/3000 mile warranty that covered everything but the engine. I ended up putting valve cover gaskets/spark plugs on it (550) and struts/shocks/stabilizer bar/stabilizer links (650) and tires (550). What the warranty has been nice enough to cover was lower ball joints, transmission (valve body and solenoid packs) and thermostat. All in all, it ended up costing me closer to $13000 dollars with all the other little things. But whatever........... :L
PS. The picture is in my garage with more to come soon....
