My agreement with the dealer seems to commit to MSRP, which is listed on it as $38,500. However, the fine print says that the price could be higher if the cost to make the car US-compliant goes up (e.g., if it costs $1000 extra to make the front end pass the bumper test, they could pass it on to me). When I asked about a premium (I think I used the indelicate term "dealer gouging"), I was assured that would not be the case in Beverly Hills. Since they cater to those interested in much more expensive cars, I'm hoping that they stick to this. But with car dealers, who knows?
Many of you have indicated that your deposit is refundable. I think this is true in my case, although my paperwork doesn't seem to address that explicitly. In any case, I have no plans to test that.
