Yes, it is sure that cars can "marry", as weird as that can sound...

You raise a good point with the problem of cars models... It's something I am very uncomfortable with.

It appears that no, a car cannot change its model. Evidence of this is Rod Redline saying to the lemons "You guys are stuck looking like that!", inferring Pacers and Gremlins have no way of changing the fact they are Pacers and Gremlins. And indeed, no car in the films is shown changing of model. However, it certainly is possible to heavily modify a car, like we do in real life with tuners. This is seen quite often in the films.

So car would not be able to change their model. This has many weird implications. It makes that an international competition like the World Grand Prix, with racers from different leagues, will come at the cost of seeing a rally car racing against a F1 car... And that cameos of real persons go all wrong, because a car and its driver, are in real world, two different entities : a human can have more that one car, and one car can have more than one passenger ! So I'm afraid Schumacher is stuck as a Ferrari... :s

One can also wonder: does this mean a racecar never will be anything else than racer ? An airliner never will be a fighter aircraft ? An ice cream truck will never be anything else than a ice cream truck ?... Some people even conclude a cheap car never will be anything else than a poor outcast, while a luxury car will always be a wealthy important dignitary... I disagree. Doc Hudson was a racecar, but he was able to become a doctor. Mater is a tow truck, and yet Cars Toons have shown him in all kinds of situations. The head lemons were lemons, yet they were wealthy (although by criminal means).

The basic problem of cars from Cars is that in this world they are both cars and humans, and humans are very different of cars... Cars are massive block of metal, that work by burning gas and rubber, and that are in some ways much less flexible then humans. Yet Pixar succeded to create belivable, realist speaking cars, which I think, is a huge achievement.
