Golf GTI purchased a year ago. Precisely to report to the sales network of Via Fulvio Testi: assisted by a very young seller. Everything is fine until the contract is drawn up. Then endless difficulties to contact him either by phone or by e-mail (no reply). From "good seller" ......... I was swiped by the car that, in relation to the power and the displacement, would have been parca in the consumptions and that I would have come back to him to confirm his truthfulness ??? words.
None of this - the car immediately turned out to be shamefully thirsty. So he thus played a possible new customer to put in his wallet !!!!!!!!!!!!!! !!!!!!!!!!!! Professional fairness is not an optional ............
