It is only a decision you can make. Are you looking for a consensus? What do you need? We all bought Crossfires because they where what we wanted and probably not what we needed. If you are going to need a back seat and the crossfire is your only vehicle you will either need to trade or buy additional.

I consider a Crossfire a luxury it was something that was not as much a financial decision as it was more a hobby or fun decision just like a boat or other recreational vehicle.

I think you have to look at it from the stand point of your own personal needs first and wants second. Gee I sound just like a Dad, Sorry but this is an opinion and you asked for it.
