There is a reason the VW is much cheaper with much lower mileage. The saying goes "payments or maintenance", and when your initial purchase price is that low, it's gonna be maintenance. And my God do VAG products have HIGH maintenance costs. Parts are expensive, labor is expensive, and yes they begin having tons of issues around 100k miles/160k km..

Remember your first car is your FIRST. Stop looking at features beyond "does it drive down the road" because at the end of the day, those "nice" features don't matter to get you places. Later in life when you have more free cash you can start looking at niceties, or even modding the car you already have. Right now you need the most rock solid mechanicals you can get and everything else is secondary.

160k km (?) is not high mileage at all in my mind, especially for Japanese built toyotas. Almost everything I own in the US spread across Chevrolet, Honda, Cadillac and Subaru has more than 200k American miles (321k km) and is more than 20 years old, and while they've all needed some wear out maintenance, they all run and drive fine.

You just have to be scrupulous about inspecting whatever you buy. I try to avoid car lots and buy private party sales only. I don't know how Europe is but US used car lots are wretched hellholes that usually are trying to flip damaged auction or repo cars as quickly as possible with high markups. Have a mechanic you trust do a real inspection to the car before purchasing- getting it up on a lift to poke around underneath, dip fluids, and check for hidden damage is ABSOLUTELY critical.
