You can get a used Fuzion (and maybe a Raptor) at a Carbon (new) price with both of those options. We bought a year old Fuzion with all the options (except the patio, which I didn't want) for the same prices as a lesser Carbon was new. We did a good hard look at the Fuzion and even a year old, it appeared new with no issues.
