Looks nice but the E400 MMC is the only suitable double deck offering as far as I'm concerned for anything outside London and with the R&D that ADL put into it and with the exception of the likes of Coast Castles, X93 and TTX, a well fitted and set up Cummins 6.7 unit combined with new bodywork and electrics will deliver good reliability if well looked after. Sorry but a 5 litre engine is absolutely no good. ADL could even introduce a B8TL chassis at somepoint when Mr Souter is looking to replace his N230UD versions for long and demanding routes. It looks good and could give the B5TL / Gemini 3 a good run for it's money but for normal suburban and mid range interurban work double deck work, the MMC wins hands down. Sorry but unless Optare either insert and to a high standard fit at least a Cummins 6.7 unit, they've got no chance of any orders.
