I am looking at a 2015 RR SC here in the Houston area. The local LR dealership has the unit, but it is not a CPO. The dealer is telling me it cost them about $5500 to CPO the car. I am just wondering if anyone here knows the true cost to the dealer to CPO it. I don't mind paying some money, but I also don't want to pay $5k either if I can help it.
