Project status

• 26 cars were total measured in point “0 km”

• 17 cars were measured in point “15000 km”

• The rental of the cars are not easy because mainly of the following points:• we need it in any case for the second point (15000 km) no rental service can ensure this• a clear history of repairs or services is necessary
