Hello and yes I am asking for advice so up front thank you for reading my post.

I am looking at buying a 2 owner 2015 Land Rover Discovery Sport SE with 88,000 miles. It has a clean car fax. And rides and runs great. The dealership let me take it home to show the wife she loves it. My question is there asking 18K for it..and I am fine with doing my own oil changes and basic maintenance..The car is extremely clean and like I said rides great and sounds great. It has no recalls on it.

What else should I be looking for that I don't know about it. And what type of warranty should I buy with it. And just in general how does price sound ?

Thanks in advance
