Used cars in Genf
Geneva is almost entirely surrounded by France, and the French market is the largest one immediately nearby. Note that cars registered in France need a certificate of conformity so that testing in Switzerland does not become involved.
Buying a car in Switzerland
In Switzerland the periodic roadworthiness test is called the MFK. Buying from the EU attracts customs duty, the vehicle tax and import VAT; for a car with EU type approval the effort stays manageable. Vehicle tax is set by the canton and differs considerably between them.
