We went from RX400h SE-L to CT200h SE-L Premier.
And we really miss the RX!! :(
Good bits of CT vs RX:
New generation hybrid drive system- EV mode, nicer gear selection, sport/eco modes
13 speakers- the sound system is improved with bluetooth connection to iPhone
SatNav no longer locked when moving
Easier to park
Bad bits:
Seems to be more road noise
Obvious things like less space
Suspension too harsh for my liking, I like the floating sofa ride in RX
SatNav screen is a slightly too small
Lexus doesn't seem to have lavished same the level of luxury on the CT, which isn't surprising given they are at opposite scales of their range. For example only the driver side is electric (at least for UK models).
