Thoughts on my 2009 Wrangler. Keep it Sell?

Hey all! Figured this is as good as a place than anywhere to get some advice.

I currently have a 2009 Jeep Wrangler Unlimited X fully stock. Second owner after purchasing in 2020. Currently has 114k miles. Actually we just passed the anniversary as it was 3 days before, well... Nevermind.

Anyways, I'm picking up my new ride early next week. My first instinct was to just keep it parked, or use during the handful of days we have a year in my region where I can take tops/doors off. Additionally, maybe keep to slowly mod, etc. Important note, mudding, etc doesn't interest me.

Since, I received an offer of $8500 to sell. Jeep is in great condition appearance wise. Most are surprised when I tell them it's a 2009. Mechanically, I'm starting to get codes more frequently. Recently had to replace plugs/pack for misfire and the radiator. Also getting the random emissions code that comes and goes.

1. Should I recognize I'm not a jeep guy and just sell?
2. Is it worth keeping - Thinking it's at/near the bottom of value?
3. If selling, is this a good price?

Just looking for feedback.

Edit: Typos.

Thanks!
