Tim,
Just my opinion FWIW:
Get the car that most arouses your passion. Leave the practicality at home with your Toyota or Beemer.
The roadster does it for me. Loud?.. wear ear plugs on long trips, or you could go with under car exhaust. Rain? not too worry, you won't melt... drill holes in the floor pans so it has a place to exit the car. (not joking). Don't stop. Just drive through the storm while enjoying the look of disbelief on your passenger's face. You'll laugh about craziness like that for years to come. Trunk space? pack light. There are laundra-mats and stores all across America; we're not talking about going on a safari or anything.
Remember, not everything worth doing in life is about creature comforts. Mountain climbing, camping, bicycle racing, marathons come to mind.
If the coupe gets you mojo flowing, then that is the one for you.
This is a TOY.
Which TOY have you really been day dreaming about ???
