what you are asking, is,
is mercedes stupid.
chryslers decision to allow some dealers to do this on the pt crusier, lead many to vow never to buy a chrysler vehicle, even if they offer a 50% discount off invoice.
it ruined it not only for the offending dealers, but also, for the dealers offering a normal discount off msrp on the pt.
the vow was especially true for those who liked the pt, and were going to buy one. but of course, never did, never will, nor will ever buy any chrysler product again, of any type, at any price.
mercedes did not become the most prestigious production automotive company in the world, by being stupid.
while mercedes did make an error of judgement to get involved with chrysler, mercedes righted the ship, by severing the chrysler affiliation.
the smart is gold. if they add hanky panky overcharging, and huckster the smart, smart gold will revert to fools gold. ie, worthless, or worse, with losses forever in the smart lifecycle.
they should be thinking of offering 'easy to qualify for' discounts from msrp. for example,
1) for cash purchases, (cashiers or personal check paid in full at delivery), a -1% or -2% cash discount from msrp.
2) a good reservation customer simple grocery gift bag at delivery, containing a) approved oil filter, b) quart of recommended grade engine oil c) approved convertible top cleaner & brush, d) approved spray can of upholstery protector, e) floor mats, f) $30 gas gift card (1+ later thank you fill-up), g) 5 year discount coupon for one extra exterior panel set, h) one year discount card for any smart products and services under $500.
causing customers reinforcing good mercedes thoughts weeks, months, years later, of
'thank you good guys, thank you. i'll be back.',
without mercedes employees having to even say another word.
