I've had two mark VIII's in my life. I haven't had a big problem with either car. I had a 97 Lsc and a 94. My 94 i picked up for a 1000 and i literally have not had to replace anything besides brakes and tires.
It's got a lot of power. I love the way the car looks. My 94 gets 26 mpg right now. My favorite has to be that original air ride though, it's so smooth
My only suggestion would be to bring it back. Such a beautiful car. I have no idea what Lincoln was thinking
