First of all, there's an impressive variety of both high-end and economy rental vehicles in Guadeloupe. What you end up going for depends on your funds and what you plan to do. Prestige vehicles are hard to beat if you're all about comfort and class. If you're splurging, why not pick up a fully kitted-out SUV, or perhaps a cushy mid-sized vehicle? Otherwise, if you just need a set of wheels to get from A to B as cheaply as possible, you're better off choosing an economy vehicle (or something else that won't blow your budget).
