1967 Auto-Universum Hard Cover

[ted]

I believe we have all seen the 289 Sports AC unit with the distinctive gaping mouth grill. The AC 428 convertible
unit's grill is wider. The 428 convertible has a length of 174 in vs. the 289 Sports' 156".
428 convertible has the automatic tranny option vs the standard trans. only of the 289..
The 2 cars do not in any way look alike, yet they are both A.C. Cars Ltd.
The 289 A.C. Sports car is the one that we see either stock or in after market fiberglass. Would that make the
428 convertible the more costly and valuable??
