The Panamera is an absolutely amazing car - great handling, incredible interior, and Porsche all the way.  The 4S Model is probably the best deal in the line-up (but, will never be able to match a Tesla S for brute torque and acceleration).

But, the all-electric Porsche Taycan is coming out later this year or next year, which is loosely based on the Panamera - and is supposed to be a direct competitor for the Tesla Model S.  If you are willing to wait a bit, that might be a very interesting alternative.

I believe he said the $175k was after taxes.

If you want her to buy a Porsche instead, tell her to look up how much the manufacture of electric cars (especially the batteries) actually harms the environment much more than normal cars.

Also, where does the electricity on the island come from?  If she is an environmentalist, she might not want to drive a coal-powered car.  

ETA:   I just looked it up.  Most of the grid (3/4) in Hawaii is powered by PETROLEUM power plants, and the rest is mostly coal.  So a Tesla in Hawaii is basically a petroleum powered car.

Even though I give electric cars shit, my wife and I are planning on moving to Kauai in about 10 years, and IF there are decent electric pick-up trucks on the market at that time (which I expect there will be), we fully intend to buy one - and then slap a bunch of solar panels on the roof of the house.

Man, some of you guys in this thread are downers.

Sure, it's important to be financially responsible (and I am a HUGE advocate of that), but it's also important to be enjoy life while you are young enough to enjoy it - and not just live like a pauper, looking forward to the well-funded retirement you might never live to see.  A BALANCE in those things is important, IMO.

As the philosopher Philip J. Fry once famously said "It's just like the story of the grasshopper and the octopus. All year long the grasshopper kept burying acorns for winter while the octopus mooched off his girlfriend and watched TV. Then the winter came, and the grasshopper died, and the octopus ate all his acorns and also he got a racecar. Is any of this getting through to you?"

Case in point:  My wife and I save a lot, and have been for a long time.  Our financial planner/managers are confident we are very much on track for a very high level of income during retirement, and they are currently helping us figure out how we can manage to buy our retirement piece of land in Hawaii now, instead of waiting until we retire.  So we are doing everything right from a financial perspective.

BUT, we also drive the cars pictured below (which I talk/brag about incessantly ).  Part of the reason for that is that we also want to enjoy the present.  When we retire to Kauai, cars like that will be pointless (because of the small size of the island, low number of roads, etc.) and we will be old and useless.  So instead, we've decided to "splurge" on something fun like that, while we are still in our 50s and reasonably "young."

On the one hand, of course massive expenditures on something frivolous like that is incredibly "stupid" from a financial perspective, but on the other hand, it is actually IMPOSSIBLE to say whether or not it is a stupid decision.  If I had decided to put the $150K towards our mortgage, or into savings, or towards the land in Hawaii (instead of buying the 911) then that would be an incredibly smart decision - IF I live to retirement age.  On the other hand, if I die (or cancer, heart attack, comet hitting our house, whatever), the day before I retire, then it would have been an incredibly stupid decision to delay gratification to a time when it never actually occurs.  So the decision has to be partly based on your realistic estimates of future longevity, health, mobility, balanced against the present enjoyment you would receive.  (On that topic, my wife and I always laugh when our financial manager talk about the models for our retirement, and how they are shooting for 90% chance of having it fully funded until we are 95 years old ... because nobody on either side of our families seems to ever make it out of the 70s )
