any recommendations for an ever-lasting car with low tco (gasoline, maintainability, no weak points, good spare-part supply)? love my 2001 passat 3bg, but after 24 years the electrics are slowly dying... plus corrosion is on the move forward... and with 10 litres per 100 km it is not really efficient (unfortunately not a diesel)
