I got bored and I checked trade in value for my C55 with 16,000 miles.
KBB:
Condition Value
Excellent: $27,625

NADA:
TOTAL PRICE $45,425

I really hope KBB is having some issues with their data / website.. .

Um...I got this:

Condition Value

Excellent: $49,480

Er...thats with Retail, nevermind.

For some reason same yr M3's are going still for over 50k. Is it just the mark up over invoice or just the MB depreciates a lot faster. If the M3 came in a sedan I would have gotten that due to the resale value.

I saw that too and check and comprabably equipped C 320 and the 320 was worth more. That immediately told me that the C55's value was a gross error. I've seen this happen before. Once an S55 was worth less than a
S500 from the same year, mileage and condition.
