both are equally good for me, TOYOTA has always produced remarkable vehicles in the luxury car segment... this is just one example
Mark X does not fall in the "luxury" segment. It is a middle segment car like Accord, Camry, Mazda 6, etc. It is considered a medium sized sedan like others in the catagory.
Crown is classified as a luxury car and has several luxury features.
Comparing the two is a stupid thing to do, Crown costs twice as much as the other (relatively). Crown has bigger engine sizes, a bigger wheelbase, a roomier cabin and options which are not even remotely available in Mark X.
Please do us a favor and don't compare the two; people on other sites are begining to think we're the stupidest beings in existence as we love comparing bananas with chocolate cake.
Just my 0.02 RS.
