I've been growing mine outside. During our recent heat wave we had quite a few days in the 90's in a row, including one up to 99, with lows around 68-70, and all my D. regia and Darlingtonia are fine out in full sun. Having a reasonably cool night after these hot days helps them endure the heat better, though even with that I'm sure there's a limit to how many hot days they can handle in a row.
I will say that your garage sounds far too hot, and if you're worried about keeping it outside (especially if it's a newly-acquired plant that may not be adapted to those harsher conditions) then the windowsill will be your best bet. Add some supplemental light if you need to.
