hi inertia,
the goto functionality doesn't take up really any additional space on the mount.
the flex tube allow the tube to be shortened for storage. I would
guess my 12" flex tube would be about 30cm shorter when retracted. There is no way I can fit my tube in an upright fashion in my car, it lies across all 3 rear sets in my XR. You might have a chance with the 10" it would probably retract (length-wise) to around the length of an 8" solid tube - but it would be good for someone to measure it for you.
the focuser is good. infact I find the build quality of the SW better than GSO overall (stiffer spider vanes, better springs, can attach DSLR directly without moving the mirror [not sure if GSO has fixed that yet] etc).
