RX 450h SE-L vs SE-I differences

[oldieish]

Apologies if this an already well trodden path. I couldn't find anything using a general search.

Other than the seats, sound system, sun-roof and air suspension (sounds a bit like what have the Romans done for us . . .) are there any other differences between an RX 450h SE-L and SE-I ?

I'm not bothered about the sun-roof nor the suspension but I do prefer the SE-L seats (also those in the RX 400h). Is it possible swap the seats between different/later versions/models? Also is the Mark Levinson unit retro-swapable to any benefit? Or is the standard set-up generally sufficient?

The SE-L is the top of the range and so has all the toys, bells and whistles.

I don't know about the seats. The SE-L seats may physically fit in a lower model but I doubt the seat toys would work because I don't think the required harnesses and/or ECUs would be there.

You may be able to swap the ML audio system into a lesser model but I doubt it would be financially viable given the cost of the extra components you'd need and the amount of labour involved. Plus, the standard system is great anyway.

The SE-L gains the following over the SE-I:

LED headlights

Mark Levinson audio

Extendable under thigh support on the seats.

Heads up display

Ventilated seats

Illuminated scuff plates

Camera on passenger side mirror, I believe Lexus call this 'side monitor'

Air suspension.

As for for switching seats and audio, with enough money and time anything is possible. Whether it's financially worth it is another question.

I have attached a PDF that highlights the changes in more detail, you may find this useful.
