Just got rid of my 03 after spending thousands on everything from new control arms to breaks and rotors, exhaust, wheel bearings and just about everything except the engine. Then the engine started making noise and I sold it for very little-as dx the engine problems would have taken many hours of mechanic time. I was nearing 140,000 miles and everyone I talked with expressed surprise that a Nissan could have any engine problems at 140k. I changed the oil at 3 month intervals (never had the oil light on despite the mechanic saying ti was low when the noise occured). What has your experience been? Should I have been able to easily get to 200K without spending a ton?
