I have a 2003 4.6is X5, Dinan Stage 3 setup. I have about 161k miles, mostly freeway. It's not my daily driver. My X5 is in excellent condition and stayed on top of all the required maintenance and preventive maintenance. I've recently replaced valve cover gaskets, timing chain gaskets and vanos seals. No leaks. All the coil packs and plugs, installed stronger torque converter, belts, water pump, and a lot of other minor stuff to keep it pimp considering the rarity of the X5 S3.
