89k miles when we got it, now 250k. Still runs fantastic, just burns a quart every 2-3k mi. Online Lincoln forum helps greatly to pinpoint repair issues and save repair costs. Same chassis as Crown Vic police interceptors so rodding mods available. Comfortable, huge interior and trunk, gets 24+ highway on regular gas, 21 mixed. "Greener" than most Subarus! Replaced expensive rear air springs with coils, $150 vs $2000, added Sensatracs and you can't tell the diff in the ride. Oil smoke problem at 150k miles is fixable, it's the right bank valve seals. 99% of perceived engine and tranny issues are cured with fresh Motorcraft copper plugs and Motorcraft plug wires every 50 k miles.
Bought this car last year and I have put 20K miles on it. It has always started right up. At 176K the engine burns a little bit of oil. I average 20mpg with a combination of city (25%) and highway (75%) miles. The only issues I have had were the air suspension, climate control computer going bad, hinge pin going bad and the cornering lamp lens falling off.
I have always had trouble finding a car that could handle my girth, but after 20 years of blood, sweat, and tears I have finally found a car that is ideal for the obese man. The Lincoln town car can easily handle a driver weighing up to 600lbs, and I being a few pounds short of 480, am a very fortunate man indeed. Well, need I say more?
