The 10" scope is more than capable of fitting in a sedan, its the dob base that can be a hassel but you can always collapse it if need be.
If your going towards Astrophotography stay away from the flex tube.
1. its harder to mount you need specialist stuff to do it
2. I have my doubts that it can hold the secondary cage strong enough. My full tube flexes a bit.....
Look at my website as I have done what you are thinking of doing. and once you go to astrophotography itll be a long time generally before you go back to visual, and you only go to visual because you get bored while your setup is taking rheams of data...
