Volvo V70, Volvo XC70, Audi A6 Avant all diesel

After long research, the following vehicles are now available. Volvo V70, Volvo XC70 and the Audi A6 Avant, all with diesel engines. I would like to buy all three of them, but as that doesn’t work, it comes into play 🙂 There are about 7000 to 8000 euros available. After a lot of reading in different Volvo forums, it looks as if between the two Volvos, the V70 should be preferred and the best i After 2005, something was probably changed on the engine (DPF?) and there are probably problems. What is it like with the Audi A6 Avant? Are there also models in the price range that are not recommended? Should there be, but no longer know which and why. Which models are recommended? Last but not least, which vehicle would you prefer? The Volvo V70 or the Audi A6 Avant, as diesel of course and why? Thanks already for your answers 🙂
