Hi
Multipla for me is one of the ugliest, but plenty of other competition including the X6, Peugeot 1007, Smart Four 4 (or is that 4 Four, or For 4?).
Heard a story that when Lotus were developing their 2L twin cam engine (used in the Esprit), it was found that the bore centres were the same as the Vauxhall engine. Vauxhall supplied 3 Vivas which had the Lotus cylinder head grafted on to the Vauxhall bottom ends to help with development. Lotus gained some mules while Vauxhall gained some knowledge of how the bottom end would cope with rather more power than it was designed for. Apparently the resulting stock looking vivas were rather rapid.
All the best
