The options are unreal, I saw C&D had a Boxster (non-S) with ceramic brakes, paint etc. and it was MSRP like $75K.
I can easily see 911S or 4S costing $110K. Not saying they are bad and probably you don't need all the options but like the M3 where it's easy to get option on top of option but just imagine Porsche has 3x as many options as BMW.
The 911 will be better than the M3 (less weight) and may not have GG tax but at a $30K higher starting point you can buy 10 years worth of gas for a M3 for $30K
