Since you have all 3, what is your opinion, in regards to ride,build quality, how they drive etc. ?
That's a difficult question to answer. They are all very good cars. As far as build quality, I think the 67 Imperial, is the most impressive for its time. All the chrome, inside and out, the quality of workmanship really shows. I wish this was 1967 so I could have seen it before the span of time hadn't taken its toll. Don't get me wrong, it's still a great car, and I love it, but it's 50 years old! The handling is still very good, a little play in the steering box, but not bad. Very smooth and quiet, plenty of power. My biggest concern is the front seat foam crumbling from underneath. Yellow powder all the time on the floor.
The 73 Imperial is probably the most eye catching one of the bunch, and the smoothest to drive, handles like a dream. Every where it goes it gets attention, probably because of its size and distinctive look. King of the fuselages! I'm gonna get her repainted next year, same color just refreshed, love that burnished red! And with the new paints they use, it will look even better!
The 78 New Yorker, has the best interior of them all! I just wish they would have used real wood instead of plastic. What the heck, Jaguar did it! The leather seats are unbelievably comfortable. You can drive for hours in it and never get tired!
All in all if I had to pick the best riding one it would be the Fusey. My 73 Imperial LeBaron. But I enjoy them all!
