To Roadsport or to CSR, that's the question

[AWL]

Some twenty years after my first ride as a passenger in a caterham, the virus has finally got me down. And the fact that I'm turning 40 next year and suffering from a growing degree of midlife crisis.
I'm about to place an order for a caterham, but I still don't know what model to take.

The car will be used on normal roads for 99% of the time. Track days will be very limited.

The available cars here in Belgium are rather limited, as is my knowledge of the English vocabulary. I want a car that I can drive over the next twenty years or so, so an entry model like the 165 isn't what I need. The 485 is a bit over the top in terms of performance for road use and I'd probably end up killing myself.
So that leaves the Roadsport 175 or CSR 175. And the big dilemma is: which one should I go for?
Spec will be similar for both cars:
screen + full weather
LSD
leather seats
lowered floors
SV chassis (no discussion about that, I'm 6'4 and I want my 7 to be comfortable, not snug)
superlight suspension (if I go for the roadsport)
and some minor things like black pack, 4 point harness,...

So, what would I go for? The Roadsport or the CSR?

Fornmainland Europe the 175 is the only available model. 125 and 140 are not available.

Is the IRS on the CSR comparable to the superlight suspension on the roadsport?

[AWL]

Decision has been taken. I'm going for the csr.
Order form will be signed tomorrow for delivery in May 2015.
It will be a long winter...

Still undecided on the colour though. Would like something classical with an edge.
Maybe burgundy with grey bonnet stripe.
Any other suggestions?

Standard dash to give a more "authentic" feeling
I'm a big fan of the bare alloy, but the time I have to invest in keeping it nice and shiny is putting me off.
And...the misses prefers a color

Nice car Zed4.
This one would get the approval of the misses

[AWL]

Is this the caustic orange or a bespoke color?

The misses has made up her mind on the colour. It will be firecracker yellow with super light decal pack.
Anyone got pictures of a csr in that color scheme?
