Hello, please tell your husband he's dreaming if he thinks he can sell his car here for "top dollar." For one thing, the steering wheel is on the wrong side! No one here in his right mind will buy your husband's car!
From the sentiments expressed by my friends, American cars in general are not too popular here due to the servicing costs and availability of (or lack of) parts. Japanese cars (Toyota and Nissan) here seem to be more popular, also European (Merc, Opel) and Malaysian cars (Proton - cheap and available parts).
However, that's not to say that there isn't a single US-brand car here. Personally I've seen Ford (most popular US brand I think) and Chrysler, but what I'm trying to say is Jap cars are more popular with locals.
