I have enjoyed the LS for it's power and ride. Very nice personal car. A bit tight in the back seat. Only problems were missing ignition which was remedied with new COP a few years back - none since then. Then there is the Ford/Lincoln A/C system. This dual temp system seems to have had a lot of problems. Controls have messed up a couple of times on this car and our Town Car. Also, lost the A/C compressor a couple of times over the 100,000 miles I've owned it. Then the cd changer crapped out. I have a couple of cds stuck in there. Sound system is great except for that. Overall, a very enjoyable, fast, safe car.
My car had all maintenance records and all original paperwork. It was a special car that had been extremely well taken care of. I love this car, it is still perfect on the highway, no sounds whatsoever inside. Has powerful pickup when needed and still has a beautiful exterior line. I love it.
As a long owner of Ford/Lincoln products this car is very understated. Very quick for a 4 door with the 32 valve/285HP V8. The only issues I have had with the car in 100,000 miles is coil packs which are covered by ford for 10yrs or 100.000 miles. If you buy one used, check with ford. They have replaced all of them. The other concern was the cooling system. IF the car has over 75K, I recommend cooling tank and plastic pipe-like hoses be replaced and whatever else the service technician may recommend. I alway recommend transmission fluid service every 40K or so to keep the additives fresh.
Memory seats/mirrors etc..
Ability to go from 55 to 90 in a blink.
I liked the electronic shocks in the 90's Tbird SCs.
When you drove normal, the car was touring and when you braked, turned hard or accelerated the car stiffed the ride for performance.
I think others like Mazda did this also.
Bring rear wheel drive sedans like this back to Lincoln.
I now have 179,000 kms on this POS and its still "nickel and diming" me to death. The front end is rattling again after it had front struts, sway bar links, and tie rod ends installed at 145,000 Kms. The E-brake light is on and beeping. I don't use it so I don't understand why it would need service. The traction control switch fell through the hole in the console for no apparent reason. I had to replace the power steering pump because it was leaking badly. The oil pan is leaking again, at least I think it's the oil pan. The coil packs (5th set) are due to be changed again because the car stutters at times and that lets me know the coil packs will need changing soon. FORD - you suck!!!
