CLE/E53 at 10% (+ rebates) out of NJ Area vs 8% (+rebates) locally in Midwest. Makes more sense to pay a small shipping bill than buy locally. Volume models will be comparable in discounts and save money/time involved w shipping.
Not all of them are of the dealers are in Michigan - scattered throughout the Midwest, but for a very brief period of time, I got to call Detroit home and am using that for all calcs.
