Depending on where the cars are assembled, the freight/import costs are slightly lower (BMW exports cars from Mexico, one of two countries - other being Argentina - whom Brazil has separate import deals with). The used car market is just as depressing. A 10-year old entry level 1.0l Fiat/VW/GM car will go for around R$10,000.00 (£3,560.00). Anything slightly more interesting will have a much higher price. '92 Escorts or '93 Kadetts are being sold for £3,000.00!
