Hi Eric,
I am fairly new to IIS as well. This is a great forum.

I think the 12" allows for approx 30% improvement in light gathering abiltiy over the 10". The views at the eyepiece are very good once the optics have been collimated.
I find the GoTo very useful. It does help to locate the faint DSO's in light polluted skies. It is also easier to keep my 5 year old interested as it tracks the objects being viewed.
The 12" Flex Tube GoTo Dob fits into my 2002 Astra Sedan. I kept the moulded packing material and the OTA fits into the boot without contacting any surfaces, but it is a snug fit. The base fits on the back seat with some care not to make contact with the door frame. If you need dimensions of the 12" I can measure it up for you. This may assist you in making determining if it will fit into your Corolla Sedan.
There seems to be plenty of happy GSO Dob owners on this forum. I went for the Sky Watcher and am very happy with it. Would have liked an SDM but that will have to wait.
