There's a difference between a rental provided for warranty work by Chrysler and a rental provided for insurance reasons.

My understanding is that if your car is out of commission via an accident caused by another driver, then the other driver's insurance has to pay for a rental that is comparable to your car. Now I could be misinterpreting this - say your Dodge Charger R/T is rear ended, insurance may look at a Maxima as a comparable performance sedan (it's not but this is just an example). Or insurance may look at the Charger as a large sedan and only approve of a Malibu as a suitable rental because it also is a large sedan. So for Atom's Crossfire, he could argue that he is entitled to a performance two seater and wind up with a Corvette, or insurance may only spring for a two seater period and Atom winds up with a Soltice. More than likely he'll get neither since cars like these aren't common rentals. But he could argue for one and also for addtional compensation if he gets something else.

Now if your own insurance company is covering the accident then you'll get whatever you signed up for. In my case I won't get a rental because I declined rental coverage. I have a second car to use as a substitute for my Crossfire if I get into an accident.

As for warranty work, Chrysler only needs to provide you with a loaner car. So said loaner car could be anything, though you'd think that Chrysler would provide loaner Crossfires just to expose more potential customers to them. Then again, most people getting loaners need something bigger.
