Has anyone experienced a problem while trying to order a new 458? I own a 360 that I purchased new from this dealer and was shocked when told the following; My local dealer said "you have to buy something else we have used in stock before we will let you order a new 458". I understand the 458's are in high demand but this seems a bit abusive. I'm considering buying a 430 from them just to get the opportunity to order the 458. I have narrowed it down to one from their used car inventory but am having trouble getting over the dollars I'll lose when I trade it back in. I'd appreciate any advice from anyone out there.
