No offence intended to any Evoke owners, but if we're applying an old-school "posh" test, I would have thought the Volvo wins hand-down.
An Evoke is a very nicely engineered car (if you can look beyond its squashed bug appearance!), but, let's face it, it's what Range Rover have introduced to allow more "less wealthy" people own a car with a Range Rover badge on the front. It's the "new-money" / flashy upstart, trying (successfully) to trade on the luxury connotations associated with the Range Rover brand (which has also gone a bit down the bling / flashy route).
Volvo, on the other hand give the impression that they know they don't have to try and be flash, so have stayed very true to what their brand has always been about - which I think is very well engineered, very safe, very robust, slightly "dull" looking cars which are close to being classless.
As such, if I were buying a car at that kind of price point, and it mattered whether it fitted in with the old-school upper class, I'd buy a Volvo over an Evoke any day of the week.
