If your wife is going to drive it too, you are going to have a hard time justifying it's size. Unfortunately, with the L322 onwards the footprint increased substantially, without much additional benefit with the interior. Good for sales in US, China etc. But not ideal for day to day driving in UK, especially if you venture into car parks and narrow streets.
Also it size intimidates other drivers and being the same distance off the rear bumper in the city or motorway as you would be in a normal car appears to incite aggressive braking to full blown road rage.
Personally, I really like RR's and I have had 4 from new, but stopped at the 2nd gen L322 when McGovern started to really chintz them up and they became the de facto purchase for footballers and their WAG's. No idea how they hold their prices now, but for me they no longer delivered on the premium of burning through £40K in a few years of driving them. Moved to a 4x4 estate when we still needed the occasional off road and towing, now to an eclass estate as we still need the space. We moved into the city 5 years ago, which influences this, and living here there's no benefit from the lofty driving position on country lanes and wading through the floods that used to be a benefit.
If you need to get very the RR itch, get a classic in really good condition, when you have the space. Obviously won't fit the daily driver requirement, but equally you won't lose a wad of cash if you decide it's not for you.
