For the past 6-weeks I've been driving our new (to us) 2007 RX350 (181,000km). Today I got the 2000 GS400 (345,000km) out and oh my God what a difference. With no slight to the RX, which is very nice, the GS is just a cut above. That 1UZFE is an absolute champ, just has so much presence. The RX is actually smoother and quieter on the highway, but the GS just rules. Nice to reunite with my old friend.
