I think you know the answer and rightly so. The Emira, from someone who has driven it for 2 hours, feeling sick, but not the cars fault, is a good car, a different car, a romantics car (this is now my favourite phrase referring to the car).
Are you going to get burnt, 100% not. Is it a great car, not quite no, at 80k there are options, but none look like it does from the outside. On the inside, engine and handling wise, there are clearly things not far away or better, the Cayman GTS being the clear overall option. At 60k it would be great value, but I doubt it will come in for less than 65/67 on the road in the end.
I repeat, IMO it's a good car, its even a very good overall package of a car. But I cant quite bring myself to say its great, even though I want to!!! However, I may when I have had it and driven it for a few hundred/thousand miles on my own, or with a young hot..... I mean on a nice hot dat. In fact, I kind of feel that like the early iPhone, it will grow on me, it has the potential more than most cars. I think the GTS I would go off and get bored of, but this will be the opposite.
You can buy with no worries at all, the car will not burn you, I simply hope Lotus themselves don't either!
