So today I brought my Sig P85 in for a long awaited service, and picked up a P85 loaner (brand new, smells great). Below are some of the things I noticed: - although it is a P85 (not +) like mine, it feels much faster. Way faster. - suspension is far stiffer - ambient lighting actually works without noise - it is quieter (way quieter). No creaks, extra noises, and less road noise - the cup-holders are worse (no grippy bits), and my water bottle fell out on a light and easy stop. - the jump seats are different (slightly). - the rear well cover (covers jump seats) is thicker and heavier (maybe reduces noise) - there is a footwell light for the driver - there is firmware 4.5 - the "leather" material on the dash and window sills feels nicer and looks a bit shinier - the J1772 adapter feels like it's made of different material and looks more robust I'll update tomorrow after I have taken a good drive in the daylight.
