Is there any tell tale signs of issues with the air ride suspension I should look for when I go take a look? I keep hearing that this is a big issue with some of the iS cars.

Also, I don't think it has the sliding rear floor and I remember someone saying its not that useful unless you're like below 5 ft tall. Well, my wife's 5 ft tall so how hard and how much is it going to cost to retrofit that?

Lastly, how hard and how much is it to put the trailer hitch on?

Thanks for any advice!
