Sat in one a few times and just like all American cars the interior isn't up to par in my opinion. 45k for an f is unheard of to me. I paid in the 60's for mine but then again i have a special build.Or with RS4, or with CTS V, especially the latter, but I have a problem with styling/quality, too many angles IMO. Never drove one, but heard that Caddy did (who knew?) a great job with suspension/handling.
45 is a great price but i wouldn't be upset to get away with 50k
