I’m not sure where people get the idea that Rubicons automatically cost $10-20k more. I spent $40k on my Rubicon; it probably would have cost about $34k (ish) without the Rubicon package. Unless there are brand new Sports for $20k that I’m unaware of. Someone else can do the math if they really care that much but the options I got on top of Rubicon were LED lights, steel bumper and body colored fenders, so add those to a base Sport and you’re definitely within $7k of what I paid.Be honest with yourself and think about whether or not you will ever use the lockers on a rubicon. You only need them for rock crawling stuff that's hard to walk over. If you're not going to ever do that kind of stuff, save yourself 20k and get a sport.
To the OP- I HIGHLY encourage you to get whatever options you want, to include none if you don’t want any. Get the basest of base jeeps. Don’t listen to anyone here- no options are “must haves.” I had a base TJ SE 4 cylinder wrangler years ago, didn’t even have a center console or cruise control, and it was the best jeep I’ve ever owned. It did have A/C though so I’d actually encourage that lol
