Sometimes it's not the perfect decision but it will work.

Sounds like you don't really have a choice for reliability if you need PHEV and German.
Double check the battery warranty lengths and call it a day.

7kw charging a must for public charging to be cheaper than gas, math below.
60kw DCFC on the Benz is really what you want.

If wife is ok with GLE450e, it also has 7k tow rating.

-------------

Math:

Gas: 15L/100km, 25c/km

3kw charging Cayenne: 37c/km because $2/hr, max out at 3kw, 66c/kw, 1kw = 1.6km or so.
5 hour topup for 30km.

7kw charging Cayenne: 18c/km because $2/hr, you get 6kw at most station, 33c/kw
3 hour topup for 30km.

60kw DCFC Mercedes: 16-20c/km with 35c/kw at BCHydro, 27c/kw at Tesla
30 minute topup for 80km.
