Well to throw a spanner in the works:
I've tried a number of times to get the DVLA to correctly classify my 110 CSW (original) as an ESTATE or STATION WAGON (the model states County SW but body type says LIGHT UTILITY 4x4). The latest response stated that a letter from LR is required which I can't be arsed to chase up yet (I'll be living in Surrey and while a bit of an annoyance I'm fairly sure I can avoid the inside of the M25 if so required).
Anyway the royal spanner in the works is that my 110 which is registered as a light utility 4x4 is shown as "Not Subject to LEZ" on TfL's website, my 88" 2.25D is shown as "Non-Compliant from 2012".
So maybe the compliance checker is slightly more intelligent than just looking at the body-type now - the 110 was previously showing "Non-Compliant" until a couple of months ago.
