Bumping this thread as I am in a similar situation as to deciding to keep SHO or not. I have test drove everthing (BMW 7 series, 5 series M, Range Rover, etc..), and nothing has everything my SHO has (remote start is a MUST for me).
I turned 67,000 miles and I havent had any major issues other than recently the rear door lock 'modulator' needed replacing ($300!!) and now my back-up camera isn't functioning (i took advice of fellow poster and ordered a $50 camera for DIY rather than give the dealer $600+).
Yesterday, a dealer ran the numbers (2013 SHO, 67,000 m) and said they are going for about 13k on a trade since they would just whole sale it. I just couldnt rationalize it. Spend $50k on a new car when I just cant find anything wrong with my SHO. Other than any reasno to anticipate any major issues over the next 40,000 - 60,000 miles?? I drive it easy and its garage kept.
Thoughts?
