It's at the new Glasgow Riverside Museum of transport. They have another one on display way up high safely out of harm's way.
..there are quite a few c5's dotted around the country in various museums.
Maybe we should try and collate a list of where they all are ?
I know there are a few at Amberley Museum near Littlehampton , plus a couple at Brooklands in Weybridge and also one at the Heritage Motor Museum at Gaydon. RadioMarty saw some at MOSI in Manchester, so they're definately out there !
