I've tried to find fair market values, trade in values etc of Lambos on Kelly Blue Book, Nada, Edmunds, etc, but none seem to have data on them. Are there any websites that you can use to find out what is a good price?

And speaking of which, what would say a good price would be for a 2004 or 2005 Gallardo e-gear with average miles (5-10k?)? And do you think the prices go up in the summer time (from demand) and go down in the winter?

Thanks,
Shawn
