Good luck with the sale dude, you might have better luck selling it without the GT2 look wing.
The C4S is quite a sort after model but most people getting them want originality.
Looks a well looked after car mate so someone will get a good one!
Think you will have to move on price a touch. Dealers selling them with half the miles for less... doubt they are as nice as this sounds though.
996 are amazing value for buyers... I sold my 500bhp 2002 turbo for £22k OUCH
