German and Japanese cars both tend to have great reliability records!
However, you do need deep pockets to run an Audi. With a Toyota your hard earned cash goes further. Plus, consumer reports indicate that Toyota has less niggles and faults than Audi has.
Having said that, Japanese interiors are not as good as German interiors! Audi wins in that respect.
I recommend Toyota for a good, faithful, reliable and solid car. Better value for money
