Just bought a 2011 Grand Marquis last week. REALLY wanted a Lincoln Towncar but way more money. The one thing I miss most in the Merc is the steering wheel only has the cruise control. The Lincoln has cruise, audio and temp controls. I can get a Lincoln steering wheel with all of the above for a couple hundred dollars. Is this just a straight across swap and EVERYTHING works? It just sounds too good to be true. Any thoughts?
