Whether that's 160k miles or kilometers, I would expect that car to last for quite a long time if its a true Toyota. I just sold my '13 Camry that was pushing 240k miles and it never had any issues and was only sold because I have a long commute and wanted to pass the car off to someone who could enjoy it for a long time rather than me running it completely into the ground in just a couple more years.
Now, I'm not familiar with the Aygo and it looks like it was developed jointly between Toyota and Peugeot so reliability might be hit or miss compared to purely Toyota built vehicles.
