Can someone please tell me whether the LX is a body on frame SUV or a crossover?
I believe the RX is a crossover but what about the GX. Thanks.

LX is body on frame.

No idea as to the RX or GX, but you should be able to find the answer on those if you check either the Lexus website or the appropriate forum for each model here.

I believe the GX is also body on frame like the LX. NX and RX are Crossover.

Thanks all. That clears everything.

Both LX and GX are body on frame with a solid rear axle. RX and NX are unibody with independent rear suspension.
