My dealer does not have a base model in stock but obviously can locate one for me. I'm concerned about the drivers seat being different. The premium package states it includes a 2-way power lumbar support. There is no mention of any lumbar support, manual or otherwise in the base JX and my dealer has not had a base yet to compare. Is there anyone who can confirm the difference in the seats for me? I tend to use a lot of lumbar support pressure and I'm concerned about buying one with testing the seat first. A manual support would be fine with me.
