The MkI and II Invaders differed visually only in detail from the Genie they replaced. Flush-fitting door handles and rear pillar vents are the biggest giveaways. Underneath, the front suspension is still MGC-based, but with double wishbones and coil-overs replacing the MG’s lever-arm dampers. For 1971-72 there was also an estate version of which 105 were built. MkIII uses the same 3.0 engine, but a switch to Cortina MkIII axles and suspension brings the need for flared wheelarches. A full-width grille adds further distinction.
