First of all, there's a broad range of luxury rental vehicles available in Shanxi. What you go with is largely dependent on your budget and what you plan to do. Specialty and prestige vehicles offer the best in mod cons and comfort. If you're splashing out, why not pick up a fully kitted-out SUV, or perhaps a fancy mid-sized sedan? Otherwise, if you just need a set of wheels to get you from A to B at the cheapest price possible, maybe go for an economy vehicle (or something else that won't burn a hole in your wallet).
