cool, so my car would definately have the infrared as a factory option? I'm not sure where a local mercedes shop is around here, I'll have to search it, but what kind of security does it have? I might just go to a mercedes dealer tomorrow...

Called Mercedes in Gainseville, they quoted me $217 for 1 infrared remote----does anyone know if that includes a cut key that whips out like a knife and whether it can be used for ignition? I test drove another persons 90 and he did have this same key.
