my back box is hanging off and making a deep sound when i drive. i just went to a garage and got a quote and they said i need a new middle bit aswel as the back box. they quoted me £200 for the parts and fitting. is it just me or does this sound ridiculous? i dont know much about lupos as i just moved from a polo to a lupo. thanks for any help. oh and where can i get a bigger back box from? jas
