Hi all, this is my first post here. I am planning to order a P85D, since it's the only model with next gen seat available (my family find the current rear seat unacceptable). Planning to get red/black leather seat, tech pack with upgrade sound and pana roof. The only thing I am struggling is the wheel and suspension option. I find the default wheel not attractive enough, but a 21" upgrade seems too costly. For p85d future owners, what are your choice? I have read the using after market wheel might have problem with alignment and warranty, and I heard about all those 19" vs 21" comparison and seems like 19" is a wiser choice. For suspension choice, would there really be a significant difference for air vs coil? From what I have heard, air suspension may lead to a higher maintenance cost. Thanks for all the advice and feedback!#!
