These days just about any new vehicle that may appeal to buyers in the 20-35/40 year old range is going to be able to fit 20s. Looking at the HUGE wheel wells of the Altima Coupe you can pretty much see they can fit 20s.
There are wheel guide magazines that come out every year that show fitments, any good rim shop should be able to advise you of fitments, and oh yeah research on the internet can get you this information as well.
One website you can use is that of
http://www.Tirerack.com. I tried to link an image of the car with 20" rims - but for some reason the link only shows the factory rims. Go to the site directly and type in your model information and size preference etc.
