great advice said:Gotta be naive to think you could really get away with it.
To be honest I'm not that concerned (or very naive). There are a lot of Elise owners who intentionally run with no number plate and I've yet hear of the Police doing anything apart from asking them to get one fitted. It would only be a possible problem (IMO and I could be wrong) if they used it as an excuse to fully inspect the car but as my car is always in tip top condition I wouldn't be concerned.
