well you can't just pick a certain look. The 59s rocked. the '60s models were awesome, the early '70s had the horizontal lights (which i LOVE) rather than the vertical lights from the '60s and the back end of the '60s SO I LOVE EARLY 70s. and I LOVE the '95 ETCs. I'd love to have one in black.
Well 68 was the last year for vertical placed headlights. the horizontal side by side headlights were introduced in 69. but since the body didnt change much from the 68 models it did look kinda funny. but it was a cadillac none the less!
Why can't I vote for '03 and up? Original styling and sales numbers are going up. Caddy's second rennaissance?
My personal favorite styling had to be in '59 though. When they were built to resemble rocket ships. Fins, lights, and chrome. Pretty much every Eldorado design was good though(ignoring the 80's of course)...
