Sorry Len - can't help you on this question. You might want to check out the english
SELOC forum for info since they've had the Elise much longer than us here on this side of the pond (although not the 111R any longer than we have). And, yes I do own an Elise - so there goes one of your theories.
Also you might want to check the
EliseTalk forums for more info, they're a little more technical than what you might find here - no offence intended PureSportsCar.
Also, since it's the standard 2zz Toyota motor and standard transmission - I'm sure a little Googling will find you quite a bit of info on the flywheel and possible replacements/upgrades. Just got to do a little work on your own sometimes...
As far as service - depends on where you live. There are 43 dealers between the US and Canada now, and specialist like Sector 111 and Blackwatch Racing are coming on. So you shouldn't have any problems with service. And most of us on the forums are "do it yoursefers" to a certain extent - so ask a question and you'll usually get an opinion.
