I managed to get some good close-ups today at Cheltenham.
First what I took to be a 4/4 Sport - but maybe not - stainless wires:

This had the spare wheel hole cut out and four 'dzus' type fasteners as if it will have an alloy cover.
Next is how the factory do the brake light switch in 2009:

Here you can just make out the brake light switch on this LHD Aero - the black box on the left.

Here's the trad leaf spring rear assembly viewed from under the spare wheel hole.

And here's the front end of the leaf spring....

Gearbox assembly +4 - this looks exactly the same as my Roadster.

Bellhousing (+4) - the yellow tube is the clutch slave pipe, so the current +4 also has a slave cylinder in the bellhousing like the Roadster. Not convenient when the seals fail....

Here's the rear suspension (nearside) looking forward:

Couple more to go.....
