I'll give you my run down - but I am not an expert.

I washed mine last week in the garage (which has drains). Washing it was pretty easy - not a whole lot of car to wash. It really wasn't very dirty either.

I use either Meguiar's Gold Class wash or Turtle Wax Platinum/Emerald or something like that.

The wheels take a good bit of time and these Crossfires are notorious for the brake dust. I use a Meguiar's wheel brush (soft) to clean them (I don't use any wheel cleaner, just car wash soap).

For the ragtop, i used a microfiber mitt and rinse well. After you dry your car with a shammie or microfiber towels or the like, if you let the car run with the heat up, the extra moisture in the ragtop will come to the surface and you can get it pretty dry. Also, don't retract the top until it is completely dry.

I polished and waxed mine last week too. I started off with Meguiar's ColorX polish, put a coat of Meguiar's Gold Class wax, and topped it all off with a coat of Meguiar's NXT Tech wax. It is smooth as glass.
I did the polish one day - 1 wax the next, etc. Probably a couple of hours each day.

On the tires I use Meguiar's Endurance or Turtle Wax Extreme Shine tire gel. You use a sponge type thing to put it on. They both work really well, last a long time, and don't spin tire dressing all over your car.

If the car gets dusty (since it doesn't get driven in rain or snow), I use a California Duster and it works really well.

Hope that helps.
