I have a 2001 Land Rover Defender 90 diesel (station wagon style-seats and windows in the back).
Earlier this year, i received the letter from tfl explaining that was liable for the LEZ charge – I was pretty shocked, especially as I live in the zone and would have to pay £100/day!
I enquired about fitting a filter to make the car exempt, but was told it would cost about £3k.
In the end, I found out it was because the car was registeted on the V5 as a ‘light utility vehicle’. I managed to get it re-registered as an ‘estate’ which makes it exempt (required a letter from Land Rover UK explaining that this model was originally built as a station wagon [estate] and therefore should be exempt).
Bit of a pain, but I now have one of the very few LEZ exempt Land Rover 90s in the country, and it’s a supercool Tomb Raider edition. As it happens, I’m now thinking of selling it if anyone is interested…
Cheers
Nick
