Dealer is offering an upgrade on our 2018 JLU Sport 4 dr that we bought brand new. They say they get brand new rubicons and add lift kits, wheels and tires and sell the take offs for $1,800, inlcludes install of Rubicon Lift, Wheels and Tires (Brand New). I know nothing about this. Is this a reasonable deal? Just looking for a slightly more aggressive look. My wife's vehicle (we are 50). Maybe some light trails but have not desire to have major lift or major off roading. Any advise is much appreciated!!
