Hey Val...long time man.
Glad to hear the Aurora has served you well, and if you feel its time to get another car (I cant use the term upgrade...I'm sorry) then the SSEi is a fine choice.
I cant offer any other advice besides saying, go drive em both and see which one turns your crank. And if you can get a decent trade in on the Aurora, then thats even better. You will miss it though. Can you afford to keep both?
I'm going to have a real hard time parting with my car when the time comes thats for sure.
