cv4n2...please excuse my ignorance, but are you located in the the US (I'm sorry I don't know where the location you listed is) If you are not in the US then that's why you are able to get them easily.
03BMW- I don't think the guy was an idiot or brushing you off. The DOT regulation is a US thing, so people in other countries can easily buy clears for sedans (which I think might be that case for cv4n2), There have been a few people that have managed to order them and have ended up receiving the wrong set, others where able to get them before the DOT regulations. Bekkers imports them, that why the are able to get them.
Good Luck
