Hi, I am looking to buy a jeep for a fun car. Taking the dogs to the beach riding with the top down, etc. I am looking at a 2018 unlimited JK Sahara model with the altitude package. Back up camera heated seats tow package. It’s very nice. 143,000 miles. One owner. One accident which was a light hit on the front corner of a deer. Carfax is clean oil changes every 4000 miles brakes done trans. Fluid flushed. Nothing else really done to it. Pictures are below of the undercarriage. Doesn’t look very rusty to me. Any thoughts and advice would be greatly appreciated. Not sure if this is a good buy or not. I can probably get it for $13,000. It is at a Chevrolet dealer. Unsure of what to do.
