I lived behind this dealer for many years. It's now a Vauxhall/Renault/Skoda dealer under a different name. Saw this on the back of an MGB GT at a recent local event.
I saw many things happen at that garage including someone making off with a 4-litre XJ-S, their lovely Landie Series 2 breakdown truck, saw the Montego before it was officially on sale, sat in an MG Metro Turbo aged 11 and declared it needed 5 gears. Salesman hated me for that!! Happy days
Nothing points at bad engineering more than creases in Gaffa Tape.
