No. I would NOT do it. 28 i or 35 i in a country where you can drive 70 mph ? what does it matter. And BLACK in Florida ??? You must love the heat inside a car.
The colour you have now is way better. And than this: trading a 2014 2.8i for a 2014 3.5i doesn't make sense at all.
Wait till the completely new G01 comes out next year. Than you might take a 35i if you really want it and otherwise get the G01 28i again.
I am sure, if you make this decision now, you will regret it in one year from now !
