I own a 60 model with 19" wheels and tech package and have been driving it since January. Over the weekend I took it in for service (which was a great experience, by the way), where the San Rafael, CA service center gave me a P85+ loaner with 300 miles on it. Having driven the P85+ for three days, I make the following observations:
+ All things being equal, having the extra range is good; there's something psychological about having a rated range of >200 miles versus below - it's pretty absurd, because for normal driving it is totally irrelevant
+ I actually prefer the 19" wheels to the 21" wheels - the ride's a little quieter and more smooth
+ P85+ is obviously quicker, but for daily driving I am not sure I need/want that extra speed
+ Whatever that suede headliner was seemed as if we were trying too hard; in fact I saw some stains that looked hard to remove
If I had to do it all over again, I'd probably get a larger battery, but keep everything else the same. Hopefully with the battery swaps and future upgrades the range issue will be a non-issue. The 60 is plenty fast for every day street driving.
There are obviously people who will just want the top-line of everything; more power to them, but all things considered, the chance to test both models on an extended basis confirmed that I am very very happy with my purchase.
