Rental higher could be a reason. Most are old birds, I saw a few
times kenna book at expressway. They also quite difficult to get
relief, rental too high for relief, but diesel consumption is
surpisingly low for mercedes, this German engine really make very
well, fine and smooth, good fuel nozzle, no diesel leak.
Their Rpm very constant and smooth, unlike jap and korean, sometime
press only, diesel $0.10cent gone, sometime ok, that is why
sometime you notice your wish or sonata can pick up so fast,
sometime cannot.
But you right, they like to drive fast and cut in here and
there, afterall, they are consider Limo, a class higher maybe, some
lan si lan yong type, some are good, same same lah
If you take in the low fuel consumption, overall overhead is
about the same as sonata.
In fact, most times I see sonatas getting booked along ECP.
