I considered purchasing an ISF whilst owning a IS300h and having a family. However prior to the 300h I owed a IS220d for 7 years and I couldn't bring myself to move back to an older interior and tech.
Considered a GSF, but decided RCF was the car for me even with a missus and 2 kids. The final hurrdle was my partner fitting in the back, fortunately she did and a couple of months later my car was on the drive after 300 mile round trip to collect it 👍
