Now Abbott Mead Vickers BBDO and Vallance Carruthers Coleman Priest will go head-to-head for the business, with a decision expected next week.
The news ends the ten-year relationship between Leagas Delaney and its biggest-billing UK client.
The agency, which recently saw its Harrods account walk out of the door after 16 years, had been shortlisted by the Korean car maker to repitch alongside Banks Hoggins O'Shea/FCB, AMV, VCCP and Atlas.
Hyundai's marketing director, Jim Campbell, is overseeing the review, which was called back in November. Campbell, who was formerly the Rolls-Royce marketing director, was appointed last October.
AMV had faced a potential conflict of interest because it is on Volvo's agency roster, but the agency has now been cleared to run both accounts, should it make a successful pitch.
Hyundai is the largest car manufacturer in Korea. Its UK sales have risen by 9.53 per cent in the year to the end of October 2003.
Leagas Delaney declined to comment on the story as Campaign went to press.
