Land Rover chassis numbers
Older Land Rovers may have a chequered past. They could have been rebuilt several times and ended up with quite a different configuration to the one they started with. Not a problem in itself, but it can be interesting to discover how your vehicle began its life. More seriously, stolen Landies are sometimes given a new identity using the chassis plate from a scrapped vehicle. So if the chassis number doesn't correspond to the vehicle you are looking at, alarm bells should start to ring.
The chassis number is usually found stamped on an aluminium plate which also gives a basic description of the vehicle. This will usually be mounted on the bulkhead - inside the cab on earlier vehicles, under the bonnet (sometimes attached to the bulkhead, sometimes to the brake servo) on later ones. The list below does not include Series One vehicles - these are very much a collector's item nowadays, and I would recommend joining the Land Rover Series One Club if you are serious about purchasing one of these historic machines.
From the end of 1979 Land Rover went over to the modern 17 digit VIN numbers - these are slightly harder to decode, but still no problem with the list below. Prior to this, 9 digit numbers, or 8 digits plus a suffix letter, were used.
