This is the difference between the DIY crowd and the non-DIY crowd. Internet parts are very reasonable so if you're doing the work yourself you can barely even remember the truck ever needing anything. An early 100 series isn't depreciating and in the hands of a non-OCD DIYer it costs roughly diddly squat to maintain. But if you're not going to work on it yourself you're probably better off with a newer 4Runner. You'll take some depreciation etc. but maintenance and repair won't be too bad even at a shop.
My wallet sees it slightly differently.
