Oh no, don't tell me it's true! :(
I thought only the IS MK 1 suffered from this with their hip-squeezing too short seats. As I have to accomodate 3 child seats in the back I was contemplating an RX300 as it won't fit/be legal in my IS with a 4, 2 and 0 year old.
I'm 6'3" so I'll better take a long test drive
BTW anyone know from what year on the RX300 has Isofix child-seat latches in the back seat? 2001 or all models from 1999?
