996 C4S Values

[stouffer]

Looking for some thoughts on purchasing a C4S this time of year. Looking for a well spec'd 2002/2003 sort of age vehicle with sub 20K on the clock as I plan to use as my daily driver. A few questions if any one can help please.
Was PSM standard? What are the 'must have' options? For me I would start with Bose and of course the sports exhaust. Are they all switchable? But what other options should I go for?
What sort of price should I be paying privately and how much will it cost me to bolt on a porsche approved warranty.
Sorry about all the questions but I'm getting excited and there seems to be quite a few out there. Incidentally the gap between a C4S and 996 Turbo seems a bit thin!!!

Thanks in advance

Is PSE the sports exhaust?

Thanks chaps but what about values. Henry has a sub 20K miler at £45K ish and privately buyers are listing 2002/03 vehicles at similar money. When 996 Turbos are coming down, surely these values are a little on the high side?
I accept they are advertised prices not sale prices but C2S are coming down to such an extent that at £45K a C4S looks too high in comparrison compared to the newer model.
What should I be looking to pay for a reasonable spec C4S?

ie 02, 20K miles, PSE, Bose and ali pack. FSH etc etc - needle in a haystack I know but values/thoughts would be appreciated.
Cheers

Thanks Adam, I completely agree. £40K for a solid modest mile C4S or I might aswell save up my pennies and get a 997 C2S.
I have money to spend but it depends how realistic the sellers are out there!!
Many thanks for all the responses/suggestions.
