Back home finally, such a long day.
So here are my thoughts.
Options
Essentail
Full leather
PDK
Sports chrono (adds DEM also)
Paddles
PSE
Bose (very hard to sell without it)
Parking sensors
Very nice to have (almost essential)
14 or 18 way seats
Cruise
Universal audi interface
All other options are nice to have but I would not consider them essential, PDCC is nice, I have it but its not too common.
Avoid power steering plus, however if you find a car that has it the dealer can decode it for you.
C4S vs C2S- Strangely the C4S is the better drivers car, its also a wide body and has that lovely red light across the back, in my view its not worth paying £8 to £10k over a C2S for it.
I just don't think its worth buying a £90k 2015 car. You can get a amazing spec car for £65k to £70k. The warranty is only around £1k per year so there is really no benefit of buying a car that will drop in value like a stone for the next 2 years.
If you really want a newer car its well worth spending the extra and buying a GTS, its the only non GT 991 thats wroth spending 90k on and I would want a 4GTS.
If you are dead set on spending lots of cash I would look for a Targa, its a work of art.
They make the ideal everyday car. I use my 991 as a everyday car (well i commute on the train now) but the idea is that I will use it everyday. The GT4 is for the odd blast on weekends and the Panamera for when I am taking long trips or with extra people.
However I could happy get rid of the other 2 cars and keep just the 991. Its a bit of a animal when you put it into sports plus mode but very civilized and comfortable when just driving around in normal mode.
Its also quite efficient, I get 32 to 34MPG on a motorway run and mid 20's combined.
As a point of reference, I sold my old 2012 991 around 4 months ago with 23k miles, £20k worth of optional extras and 2 years warranty for £62k (ish)
Some cars
Good spec, I would want to spend under £88k on this

if you can live with the red this is a epic spec

This is also really nice

This is a much more sensible buy, Its a nice spec, not too many miles, well priced. A bit boring color combo but it seems like a good car

I would have this over the above car

My car has £33k worth of options on it. Its not for sale yet but It will be at some point when I find something new.
