If it were me, at least for starters, I'd just follow what AEV has done in terms of levels or stages of an upgrade. Dealers all over the place are shipping their Jeeps to AEV to get the AEV treatment, so I think they've already done all the marketing work to figure out what a dealer is willing to spend the money on.

AEV JK200 - $7,738
AEV JK250 - $10,976
AEV JK300 - $14,897
