I brought an X3 rented and registered at the end of July 2019 in the workshop by Autovanti in Monza after having had the misfortune of being stolen from lighthouses and the navigator on 9/13/2019 and to date I have not yet returned the car 20 / 11/2019 downloading the various responsibilities between dealership, coachbuilder, insurance, renter and I pay an installment every month for having practically still not used the car at the end of July! I also note that the thieves took 8 minutes to dismantle everything without damaging the car !!! Now I wonder how it is possible for such an important dealer to leave a customer abandoned and without any information for so long and I still don't have a return date !! Simply outrageous !!! I add that last week after an umpteenth email and phone call from the insurance contact me to tell me that at most by the weekend they would give me the car back and instead we are in the middle of the week after it is still I know nothing !!!
Truly I find little professionalism on everyone's part !!!
