Seriously, I'd say that they offer you $3000 or so. You have to understand that they are a car dealership and they will not offer you sh!t for your current car, no matter what it is.
I once had an offer for $800 for my 90 300zx, trying to trade for a new 98 Mitsu Eclipse GS-T. I found a dealership across town that had a 97 GS-T with 10k on it for $3000 less. They gave me $10,000 for the 300zx. It's just all in the numbers at the bottom line.
If they were asking say $5000 over sticker, you can bet that they would give you more money for your SVT...
