2-door/4-door 4-seater coupé/saloon.

Fastest version of complex Marina range, undistinguished apart from that. Greatest under-steerer of all (early recall caused a stir) still with no character, but 100mph was possible from MGB-tune B-Series engine. TC lasted to late 1975, when displaced by GT (2-door)/HL (4-door), and plusher Special derivatives. No estate car or automatic transmission options - no proper sporting image either.
