One thing I had been telling myself to do when I went down to the dealer, yet managed to forget, was to bring my accordion case and see if it fits in the trunk. I'm afraid it won't (9.25"d, 19"h, 21"w), but if it doesn't that's ok: it'll just inspire me to think of my shoulders and buy a soft gig bag (9.5"d, 17"h, 20"w). I'm trying to find some sort of spec sheet with dimensions, but alas...
Thanks so much Fiat friends! The hard case may be a tight or no fit, but the soft gig bag is thinner on top (keyboard end) will most definitely fit. Come to think of it, that trunk may have just been designed with an accordion in mind! So excited...!
