full disclosure: I own an FJC and wheel the crap out of it. absolutely love it.
Here's why i bought an FJC over a 4R
Available with 6 speed- every car i own has been three pedal
Atrac is quite amazing. im a huge fan. pretty much standard on the FJC, not sure on the 4Rs
RR locker more easily available on the FJC.
Shorter wheelbase then the 4R
Fits larger guys, like me, better.
factory roof rack is useful to a point. better then 4R stock. your going to upgrade both at somepoint
IT HAS THREE WINDSHIELD WIPERS! HOW DO YOU BEAT THAT 4R?
And no offence, but in my town, 4R kinda screams, soccer mom/ski bum. Not that much better with the FJ but its at least less common.
Oh and i almost forgot...you cant diss on the suicide doors because as any FJC owner will tell you. I have a perfect little spot to pee on the side of the road and no one can see me. just open both doors and its your own little stall.
and they stopped making it. so that's cool. "collectible??" but the parts are basically the same as taco/4R
Cons:
small gas tank. i get like 12 MPG, which i am sure the 4R does too if your loaded like i am but i have what seems like a 200 mile range....always pumping gas.
you cant see anything out of it. you get used to it. you feel for the rocks, that's what the skid plates are for.
you learn to back into any parking spot you can when given the opportunity. Reversing is a skill and the FJC forces you to get good at it.
it is the perfect size for you and your wife and one dog. if you utilize the roof rack properly. expect any more and it ain't happening. Kids- nope. and don't expect to sleep in it. i know people who do, but i don't because i am too tall. Solution: Roof top tent. The back seat is for the dog. its bigger then a 2dr wrangler, and a happy medium between the 2dr and the 4dr. BUT NOT A JK!
They are expensive. Resale is stoooopid. i am lucky i scored a certified used 2010 6MT back when they hadn't gone crazy and no one wanted the stick. the windshield is $600. Keep that in mind when buying used.
but in all seriousness there basically mechanical the same vehicle. Same limits with the IFS and capability. just different body panels. either one would be a good choice. your basically limited to 33 inch tires, 3 inch lift and skid plates with either platform. you can get 35's but you start to break things and there are fancy SAS's out there but thats a ton of money...and 33's and plates will do more then you think. Trust me. My bone stock FJ has done some pretty rough trails.
the FJC has quirks, but there isnt a single vehicle i would replace it with. Not even a 200 series at this point. Its a niche vehicle for sure but its perfect for what i want.
Drivetrains differ from MT to AT
6MT-40/60 split AWD 4HI- 50/50 LSD when you lock the center diff, 4lo -
the MT is also geared quite a bit lower.. better stock for crawling but if you go big you change that anyways, not sure if this is reason enough to get MT over AT for some people. no need to re-gear until you get 34+ inch tires. AT sometimes have strange shifting patterns on hill when on the highway. solution is to regear lower/trans cooler ( i would buy anyways) or run it in overdrive.
AT- 2hi, 4hi w/ 50/50 LSD, 4lo
