Unless things change wildly i'm still looking at " roughly " 15k for a 4 year old decent example S3 with low-ish miles.
This is not aimed at you Dipstic.
If they are changing hands for silly money in 3/4 years then " we " the owners have only got ourselves to blame for letting them go too cheaply.
If we all stick to our guns and under cut the dealers used prices by a grand or two we'll do just fine!
If people want a quick sale then sell to the dealer for he's price , don't sell em cheaply private as that will have a knock on effect and the cheap price will become the norm!!!!!!!!!!!!
