I think you represent very well the typical customer who wants to buy a Lotus and who Lotus should be trying to please. Someone who really wants a Lotus but isn't (understandably) quite sure if it's the right choice. I'm a Lotus nut, and have been so since before I could drive, and I have had a Lotus continuously since 1973. I completely understand, and have a lot of sympathy for your position. The only thing I can say is that the Evora is the best road car Lotus have produced. It is almost there or thereabouts with other marques on fit, finish and reliability. Sadly it isn't quite there as just as Lotus eventually catches up, everyone else has moved on.
On the other hand if you want the best driving car that is available then buy the Evora. Test drive it, be surprised at just how good it is, and then regret not buying it for the rest of your life as you constantly compare your other choice with the feeling of driving a Lotus.
