Trying to trace an imported TVR into the US

[Gary TVR]

Is there any way to find who, when and/or where a TVR was imported into the US? Any import records to search? I purchased my Chimaera from a dealer who had little to no info about the cars history, and he was the first to registered it in the US. I have the MOT info from the UK, but no import info. Thanks for any help or guidance.
