Agreed here too. I don't. Have the technical details nor the knowledge, but the LX's have always felt "more" vs the Prados. Absolutely NOTHING wrong with Prados, but it feels a higher class level car. The MB analogy is perfect. C vs E vs S classes, and I am not even a MB fan, but an S Class is magnificent to sit on. Never had one but was picked up by one on a business trip once: class.
Could you please elaborate onto why you like the AHC more than KDSS? If anything, I would really miss the KDSS if I go LC250 route. The "issues" with the engine, the "cramped" space at the second row in particular, and the big grill vs the LC200/570 are really the reason why I haven't gone for one (and the cost too, but if I am going to treat myself one more time, I wouldn't mind it). The more I think, the GX550 would be !
