For the last year or so I've been meaning to pick up an E46 M3, its been my dream car for a while. However I have a couple Jetski's and frequently pull my dirtbike on a trailer so its pretty much out of the question. Being a BMW guy I started looking into X5's, particularly a 2005-2006 4.8. I'm aware of the hitch issue and assuming I can find an OEM one somewhere, do you think I will be dissapointed? I know it won't be like an M3, but I don't want a boring soccer mom car.

Also, is the X5 any more expensive to maintain than an E46 M3? Is it possible to find an 05-06 4.8is for <30k?
