Van Converted To MPV - Am I Exempt From London LEZ ?

[redgriff500]

I've converted my van to a 9 seater with windows etc and have re registered it with the DVLA and its come back as an "MPV" which was a pleasant surprise.

So as its now an MPV and therefore not a van does this mean I'm exempt from the soon to be introduced Low Emission Zone ?

I've tried the checker and it simply says:

"We are unable to identify this vehicle. Please check that the Vehicle Registration Mark and/or the country of registration."

According to DVLA site an MPV is a car so I'm guessing that means I'm exempt.
