car parts in Mexico

Writing a novel set in Mexico. I want to send the heroine to Mexico driving a car (bought in the U.S.) for which it is very difficult or impossible to find parts in Mexico. Is their a make or model of car for which that is true? (Or is it now possible to buy parts for every possible make of car?)
Thanks!

I would simply use literary license if I were you. Suburu is a brand that only relatively recently began operating in Mexico: since 2006. That might be a good make of car for you. We still hardly see them around in rural Mexico.
