everything that alex says is true. jeeps aren't for everybody. but i myself happen to think that they are a whole lot of fun. jeep is not just a car, it's a.............statement.
go to a jeep dealership and drive one. even if you're gonna buy a used one, drive a new one first. they won't know that you just wanna drive and not buy. if you like it, well you know what to do. if you hate it (because it'll be a very different experience from the rav4, then you'll know what to do then too.
driving a cj, yj, tj etc is a unique experience........you really know that you're driving.
if it isn't your cup of tea, have a go in a 2000 cherokee sport. it's a little more tame.
