Not drive it? Seriously?
I drive my 911SC daily. Screw the value. Its a Porsche and it was meant to be driven.
Here is my Boxster solution - a spare replacement engine. $2850 including shipping. 75K miles. Complete with all accessories and hoses for a direct swap. Indy shop charges around $1,200 to swap engines so I can be back on the road (or racetrack in my case) for around $4,000.
Just looking at that spare engine makes me smile - no engine worries for me!
