Having both here, in the same colour, same engine, both saloon...and liking toys.
Elite all day long for me, but the absolute first thing to go has to be the suspension. Unless your a wafting along type of driver/pikey.
Mv6 seats are probably the best sport seats I've sat in, but I still find the side bolsters on the base uncomfortable, the backs of my thighs ache on a journey more than 20mins long. Although being tall And needing to sit close the the steering wheel to mucsle my currently heavy steering about, means i've got used to a slightlymodd seating position, that i havent experimented with on the Mv6. The loss of memory function is unacceptable though IMO.
Bose is a must.
Retro fitting depends on where your skills lie.
Being hopeless at electrics, I obviously prefer to fit better suspension to the Elite, than fit loads of toys to the mv6.
Sunroofs are a pita. But IMO the odd occasion that they can be used, like today's drive through a roundabout infested town on a sunny day with little traffic and shite tyres on the back made it all woth while. Ac on, sun coming in, fantastic.

Elite on firm suspension for me. But then, it's for you, so that's not a helpfull statement.
