I'm saying 3rd gen 4runner's, as an SUV by deffinition, Sports, and Utility vehicle, i dont think much else comes close. The FJ80 is amazing dont get me wrong, i'd die for one, but i think as a cross between something amazing offroad, amazing on road, handles well, is comfortable, practical, and fun to drive, nothing beats a 3rd gen.
No jokes, i drift my 4runner in rear wheel drive, and can hit roughly 70-80kms going around a few of the corners(guessed by entry and exit speeds), and sustain it all the way through, this is because they are incredibly balanced, and mine is mostly stock(in the snow i almost forgot to mention) Ive also left guys behind whipping through logging mountain roads, because their cars would under steer too much to keep up.
Jeeps, im sorry, are all horrible, and certainly dont handle remotely well, and even the new 2 door wrangler is amazingly cheap, uncomfortable and impracitcal. 90's cherokee's were "good", nothing more, and Jeeps have been kind of a joke for a long time, especially wranglers.
The first SUV classed vehicle if im not mistaken was a Lada Niva, which is actually fantastic if you can get it to work long enough, and i think might deserve a spot on here more than others.
Suzuki Samurai, compared to a bunch of these nominees, the Samy is a real winner. Damn easy to work on, well balanced, small and amazing offroad. You should see the guys in $2000 Samurai's kick the asses of Wrangler rigs costing a good laugh more. Also easily swappable for toyota parts, like axles, a set of T100's goes on one with hardly any modification, newer Sidekick motors go in them incredibly easy as well. In countries like Japan, Samurai's are probably used offroad more than Toyota's, known as the Jimny now though.
Still, hands down winner, is 3rd gen, after market and mod support is incredible, the 3rz especially, LCE really likes this motor, uses a W59, so if find yourself turbo'd stick a w58 in there from a Supra, or if u want smaller ratio's, a w56 from a 1st gen, no modding needed.
