2010 was 4 years ago You got an amazing deal none the less.
Rust is always a concern I have.
You can probably get the guy or dealer to come down. Negotiate never pay what they ask. If you have cash even better.
Is the CARFAX clean?
That jeep is probably worth $7000 imo in the conditions you described.
I purchased mine last summer. 2004 TJ sport, manual I6. NO rust, but it needed speakers on the sound bar, needed a new soft top 87,000 on the clock asking price was $11,000 I didn't pay that.
