[Maxwagen]

Long story short, I took delivery of my "new" 330i wagon on Tuesday, but I didn't end up trading in my old car. I need to pawn it off to a lot (i.e. Carmax). I actually did bring my car to Carmax back in May and I'm fine with what they offered, but seeing as I have time (and in the event that Carmax's second appraisal is different for some reason) I might want to get multiple quotes. Is there an easy way to get a ballpark estimate from various places, rather than calling and driving around?

I tried the "sell my car" thing on Edmunds or Autotrader or whatever, and the few quotes I got in from places were garbage.
