A person whose want to decide to buy accord or camry, actually want luxury, otherwise he would be considering corolla or civic.
And if you want luxry nothing can beat Merc or BMW
For 5.8 million one can easily get a 2004-05 Merc S320 in mint condition.
Or a 2003-04 BMW 740-730D
Not Camry nor Accord can beat above mentioned cars in Looks, Value, Luxury, Built Quality, prestige, Aftermarket value and virtually everything.
If you buy accord for 5.8 million, within a few weeks its value will depreciate atleast 5 to 6 lacs, same is the case wit camry.
While if you get a good deal in buying merc or bmw then its value could be increased over next yar by up to 5 to 6 lacs. (as it already done when 745li was available for 3.7 or 3.8 million now the same car trade at 4.5 to 6 million.)
