yeah, it depends on the model of the cars..i have a corolla LE, and it come with them..an XLE and SE might have styled wheels, and some other LE's might have styled wheels as well. depends on the options packages from the assembly line.
to me, it saves on worrying about wheel theft, and having to buy wheel locks.
my 2nd and 3rd Camry's (LE models) had styled wheels, but those were lease cars
but i can assure you that hub caps ain't cheap either..they hover around $150 each...
which is why i remove/reinstall them myself..
my 1st Camry, as i left the dealership after my "free oil change"......one of my hub caps passed me on I-95....
i took the next exit, went back to the dealer, yelled a little bit.......they owned me a new hubcap, which 3 days later, i went to pick it up.
the next time, same car, Firestone sold me a set of tires, same thing, hub cap passed me, but this time, instead of doing like 60 mph, i was going slower and several cars happily ran over it..
i went back, picked it up...yelled at the manager.....Firestone got me a new hubcap.....
so, i remove/reinstall myself.
