They did develop a few UV inks that were elastic enough to wrap with, but they have some disadvantages. Where you have higher ink loads the vinyl doesn't like stretch as much or shrink back after being stretched or pre-stretched. If the wrong UV inks are used, it may look fine for a day or two then the inks will shatter like glass in high tension areas.(At one time camowraps material was printed on a Leggett & Platt printer with special UV inks.)
As crystalcoastgraphics said, Latex and Solvent both have their benefits. You just need to weigh about a dozen factors like, good local support, color gamut, speed, reliability, ink cost, printer or print/cutter work flow, rip, size (54 min but 60/64 is better), lots of others, and finally cost.
If you doing vertical panels use the 54" wide material. 60" wide panels are a pain solo, but can allow you to print a complete seamless side on some taller vehicles. No seams means less time and error lining things up... It is also nice when your selling banners by the square foot not to have to talk your customer into a smaller size banner.
I used to print when I was in KC but I'm just an installer now. If the solvent graphics are out-gassed properly, I could care less whether it's latex or solvents. At that point, the brand and material choice is more important. My material preferences are the same as Ikarasu's.
Advice, if your a last minute type of person or make lots of mistakes, choose the Latex, irregardless.
