Trust me, I am a bloke who is only 5'5" inches tall, but has a short leg/long body thing going on (I don't look too weird...) and I find the 159 a joy to drive. It still has a small element of the old fashioned "ape" thing going on with the driving position, so short legs and longer arms does help...but the seat goes up and down a lot, quite high in fact (although I drive mine pretty low down and still have a fantastic view), the steering wheel moves extensively both up and down AND in and out.....I think she will be fine. Get her in, adjust everything, see what happens, but I am pretty sure that her legs, even at that short, won't be much shorter than mine, so she will be absolutely fine I reckon.....will be interested to see how you get on. Good luck! Will be worth the fiddling about with everything!
