Oil consumption problems with Northstar engine virtually eliminated with what is termed WOT (wide open throttle)running. It appears ironic, but works. The finest automobile that I have ever owned and offers unparalleled luxury from top to bottom. OBD II system virtually checks systems and can be manually accessed for DTC's (diagnostic trouble codes) In essence, it diagnoses its own problems. Leather interior is exquisite. Ride is just like sitting in an expensive leather recliner- in a jet airplane. Sound system-CD changer & cassette player- offer flawless entertainment. MPG 24 city / 30 highway. Beauty, power and performance like no other I have ever driven................
Luxurious ride with little or no maintenance other than fluids and tires. Merely change platinum spark plugs and wires at about 100,000 miles and drive off into any sunset. Heated seats, passenger independent climate controls. All features well designed and executed.
No complaints, no suggestions, just satifaction with Cadillac quality and Northstar reliability and performance.
