Surprisingly I found another 2 Dr Range Rover for sale in the US that was from Spain also, and had a VIN listed. Using a decoder, it was made by Land Rover in Solihull as a RR (mk1), 100"wb, 3 dr station wagon, LHD and 5 speed and MY '89/90. The only item missing from the decoder was "N" for the VM engine (the list has several other diesels listed)
It has been a long time since I've looked at eBay auctions in the UK, and after scanning a few, remember why.... little catch phases like : Rust free ( meaning you're not charged for the rust ), a little TLC needed ( usually the frame has so many patches you don't know what is original).... or prime for restoration ( I don't even want to go there

)
If you go to the website above, you can click on the pic and it will go through a collection of pics of the vehicle.
Trying to think back before the web, I don't remember how I found Land Rover stuff back in the '70s and '80s... heck, I don't remember what I had for breakfast this morning.
