I moved from a Westfield to an Evora as my 'weekend' car (the Westfield would be a 340 in Caterham terms and the Evora is an NA).
I think it depends on your intended use case. For me, I wasn't getting the miles in in my Westfield. 10% of the time it was the best thing I could be driving - e.g. heading to a country pub on a sunny Sunday. 90% of the time it wasn't an option as the weather wasn't great or I was going to need to move children/luggage or might have to leave it in a car park overnight etc...
The Evora is SO much more usable and now, 90% of the time, I can use it for a journey if I wish to do so.
The performance isn't as 'raw' but I feel a lot safer. I have driven my Westfield on track and felt very exposed. I now have a different car I race/do track days in so that itch is scratched.
To summarise, I think '7' type cars are excellent and I loved mine - but it taught me they need to be a third or even fourth car, not a second, if you are to enjoy them without begrudging the impracticality. I am very glad I made the move.
