I plan to keep my GSF until I know longer need the saloon shape. Which will be once my youngest is grown. 😅
The problem with wanting a GSF is the fact that there is only 50 odd about, so the colour, year, spec combo mentality has to be semi thrown out the window and you just need to be ready to buy one when it becomes available. And even that can be tough, there was a white GSF for sale by lexus Coventry back in October which 3 different forum members were chasing none of us got it.
Just keep your pennies ready and search daily twice. You'll find one.
