Need Help Pricing A 2003 C4S
 

So I'm in market for a 996 C4S. I found a car I'm interested in but I'm not sure what I should pay for it. So I go on KBB and get the trade in and private party values. When I go to NADA, The trade in value is around $7000 less than KBB. Why is that?

Looking at some completed Ebay sales might put you in the ballpark.

Because dealers expect to make around 20% markup on a car. It's called wholesale pricing.

I own a 2003 C4S and was looking to sell it but the weather got bad in the northeast and I didn't want to have people test driving it so I pulled the ad.

It depends a lot on the miles and condition of the car. I will say that I was offered $26,500 and turned it down. Mine has 63000 miles on it and is Seal Grey with Black interior.

I think if it has between 60-80k miles on it they are going from 26k-29k. Under 60k miles you're probably looking at $29-31k for cars that are in good unmodified condition.

I will say that I've noticed that the KBB has actually started to tick up on the car, I think it might be a seasonality effect that they have in their algorithm.
