Versus the Cadillac, first you save $20K when optioned out off the dealers lot, that's quite a bit. Second, you can put the Lincoln in 2 wheel drive, giving you better gas mileage and a better ride. Third, you get an independent rear suspension, with the L, long wheel base, nothing rides smoother in this class, period. A Suburban rides like a base pick-up on a gravel road, my previous vehicle. Fourth, the seats don't need to be pulled out (third row). Not only are they roomier, the fold right into the floor. I am a large guy, the third seat is a pain to get out of a GM vehicle. My 5.4 drove over Colorado at 10K feet altitude with plenty of passing power. Love the truck @ 48,000 miles!
Only complaint is the tech package and dash and the instruments are old looking like almost trying to be retro. The new version really didn't change anything except the controls and dash. Much nicer now. Not a deal killer as the car drives and rides great. It's comfortable and fits all the gear. Stereo is great, a/c and heated seats, all add to the likability. Only other caution I'd throw out is auto running boards. If you forget about them, you may walk in to them as they deploy and forget about them as they come out and bruise your shins.
