Persons under the age of 18 are not allowed to operate a car or motorcycle in Germany. Good auto maintenance for all US specification vehicles is much harder to find than it is in the US. Local service stations are unfamiliar with cars not sold locally. A few stations do a thriving repair business on non-standard cars. All repairs are expensive by US standards. The exchange can order parts for typical US vehicles. Delivery usually takes no more than 2-4 weeks if the item is stocked at the AAFES warehouse in Germany. All other parts must be specially ordered from the US with at least a 4-6 weeks delay, with no guarantee that the part will arrive during this time period.
