Out in the east end, I have had good experiences with my dealer (Motor City Saturn in Whitby).
In general, you might have better luck if you ask your salesperson to introduce you to the service staff, and ask your technical questions when the service personnel are present.
Or, just post your questions in the forums here
In any case. "I don't know" is an unacceptable answer from a sales person, unless it's followed by "but I'll find out for you and call you back tomorrow". Ask for the sales manager and request a more knowledgeable sales representative or find a new dealership.
To answer your questions:
Top down procedure:
1. Open trunk.
2. Roll down the windows or open doors (optional, but makes things easier).
3. Unlatch the roof.
4. Push the roof to the rear. It will pretty much fold itself into the trunk once you get it started.
5. Get out of the car and press on the roof IN THE CENTER on the main cross rail to "pack" it fully into the trunk.
6. Close the trunk.
With a little practice, you can get this process down to 20 seconds (about the time you spend sitting at a stop light
).
Seat adjustment: fully manual back and forth, electric up & down.
Suspension is different between RedLine & base (I don't know all the details, but could do some web research to find out if you like -- I think it's shocks, springs, & sway bars).
