I suspect the first incarnation will be a Plus 4 equivalent.
For me the deal breaker is the pedals and steering wheel relationship. If it's Aero/Italian long legs/short arms that's a definite no.
If it passes the comfort test then I'll let the early buyers sort the teething issues, and think about selling both to buy one in a couple of years. When a range may have emerged.
Having to accept a Morgan which discourages DIY fiddling is also off-putting.
So we'll see.
