Individual model lines that were similarly sized were therefore competing against each other, yet were never discontinued nor were model ranges rationalised quickly enough; in fact, the policy of having multiple models competing in the same market segment continued long after the merger – for instance BMH's MGB remained in production alongside LMC's Triumph TR6, the Rover P5 competed with the Jaguar XJ, whilst in the medium family sector, the Princess was in direct competition with upscale versions of the Morris Marina and cheaper versions of the Austin Maxi, meaning that economies of scale resulting from large production runs could never be realised. In addition, in consequent attempts to establish British Leyland as a brand in consumers' minds in and outside the UK, print ads and spots were produced, causing confusion rather than attraction for buyers.
