Anyone own a Ford Mustang convertible? Advice needed...

[Porsche]

Hi all

we're renting a car when we get to the USA later next month, and I was thrilled to see one of the options available is a Ford Mustang convertible.

I have trawled the web looking for information, and most of the reviews discuss performance, handling etc. That's great, but I also need to know about passenger and luggage capacity, and was hoping any owners here could help.

There's 4 of us, wife and I + 2 children (6 & 8). Are the rear seats big enough and comfortable enough for kids? We'll probably have a booster seat for Zac (6).

What about luggage? We'll be travelling relatively light. We're starting with one large suitcase and 2 small carry on bags. but will also do a ton of shopping, so trunk will fill quickly
(how many Rolex's can you fit in the trunk?)

The only other concern is more the comfort of wife and kids. If we get bad weather, or maybe they all just get tired of the "wind in the hair", does canvas top work well? Will kids have any kind of view from rear seats or will they be shut off from the outside world?

We driving from Los Angeles to Las Vegas, then on to the Grand Canyon with a couple of days sightseeing the surrounding areas (Flagstaff etc). Thanks to Hollywood, I have this mental picture of us cruising through the desert scenery, (Liz is thinking Thelma and Louise, I'm thinking Duel, ha ha), but is the reality 6 lanes of smog-choked freeway? Do I need a reality check

Any first hand knowledge would be much appreciated.
