Before ELS, no you couldn't, because you wouldn't have a siren. However, with ELS you can change the namehash to stanier or the actual vehicle name, but the problem is, and I experienced this for myself, when you get into the vehicle, the car radio is on with no way to turn it off except by turning down the music volume entirely. This isn't a big deal, but I don't know what other side affects using that namehash may have, so you're free to give it a try.
