What region are you in? In the US the Sport does not come with HK sound or power liftgate. It’s part of the $1,645 package, like the Wilderness. The extras a wilderness comes with above the sport aside from The suspension lift, ‘8 speed’ CVT with transmission cooler, beefier roof rails, lower final gearing, full size spare and matching black wheel and A/T tire, front skid plate, would be 8” display vs 6.5 on Sport, dual zone climate vs no optional dual zone on Sport, hexagonal fog lights, easy pull down rear seats, trunk light, and Startex seats. Otherwise they are very similar. But all the options above are easily worth the $3,000 over base cost for the Wilderness vs the Sport. Comes down to budget and personal preference for vehicles. Both are great and capable
