Can't even get a TE without KDSS in CO, unless you drive to NM or TX--same goes for anything without 4WD. We get all the cool toys.
The V8 in the GX460 isn't that great, and the sub 50k model doesn't have the premium interior, which is what you'd really want if you're spending money on it. I hate the grille on the 460 and to get a bumper mounted/fabbed would require cutting. Same goes for lifting, your options are very limited and you'd need a shop that has a good mechanic and has access to ICON, EMU, and Toytec parts to cobble something together.
I like the GX470, it's everything good about the V8 runner and can be had for 20k in places where it's common (Colorado). There are a variety of kits you can buy to lift it. The leather interior reminds me of the old 80 series and it can be a mountain goat.
I have a 12 LE, with 17" FJC TRD wheels and the proper tires it's a great truck on and off road. The interior is "nice", but what I really like about the LE over the TE, the seats are softer.
I have a 13 TE with a hybrid Toytec/Bilstein lift I use to scramble around the mountains. I'm getting a bumper fabbed at some point but funds are spread out elsewhere (new trail tires once spring comes along). I like the new LE's, bluish one, but the chrome dental dam annoys me.
If I were to buy a 4Runner now, new, it'd be a toss up between the PRO (I like orange) and a LE. Since I go off road, I'd get the PRO--but then I like to run them lifted so I'd probably toss their fancy suspension.
I'm listing all these vehicles as potential off road projects because they're all heavy pigs and they were derived from trucks that routinely go off road.
The GX is essentially a hippo in drag made up to look like a racehorse. The crappy tires and wheels, running boards, and plastic encumber all of its off road abilities and you're going to have to do hacking and cutting to turn it back into something decent. Interior room is also sacrificed for all the suspension, tcase, and driveshaft bits dangling off the chassis.
As for "doctor cars/trucks"... some of mine are/have been...
60 series trail pig, sold ages ago
80 series mountain pig, still have it
GMC Sierra farm truck, sold for TE
FJC trail pig, sold for GM
3rd gen T4R pink milkshake, sold for parts
13 TE mountain pig, current DD
If rifles and steel target stands, and a few YETI coolers fit in the back and it can venture into a snowy mountainous hell and bring back some form of dead deer/elk, I'm good.
Sometimes the best decision is to do nothing at all...
