My Ibiza was nicknamed 'The Beast' which was an ironic name as it was a 1043i engine. It came about as my mates had an Impreza turbo, Saab turbo, williams clio and RS escorts and i had that thing.
My mrs calls the saxo 'Baby' as its smaller than the stilo
My stilo is referred to as 'The Car' or at the moment- the shed!
one of my mates had a car called Phatboi- an astra GSi
