Found this years ago on an urban exploration forum, it appears to be a stolen sierra cosworth, dumped in a dis-used railway tunnel.
Went down to see if I could get a closer look a couple of years ago, but there was a new housing development and they had put up big barbed wire fences to the entrance, could be a 4x4 with a fresh 200 block

Some poor sod is probably still wondering what happened to his pride and joy!
