Just a couple more thoughts to help confuse you further.
The Aero based +8 has very little luggage space behind the seats , I put a camera bag there for a test drive , and I was really surprised how little additional space there was , certainly a great deal less than the Roadster and other trads. You can of course put a luggage rack on the rear panel if you need.
You also have to embrace the concept of living without a spare wheel. If your motoring is in daylight hours in places that are likely to stock the tyre size needed then fine , but if you enjoy motoring through the wilder and less populated areas of this (or indeed any) country , then all you get is a can of sealant. If that is OK by you , then fine , if not then you might need to re-think things.
Lastly I know others here have vouched how the Aero +8 handles really well and the tail end is well controlled. I have a feeling this must take some skill. I found it quite challenging at around 4,000 rpm when the VANOS system opens up and a whole load more torque suddenly gets transmitted to the rear wheels. On an admittedly short test drive the conditions were appalling , cold sleet , soaking roads and not great visibility I almost got a tank slapper while accelerating up a hill in fourth. It gave me something to think about.
The only way you can decide is to test a few cars and see if you can live with the differences.
