Considering a used 2020 Prius Prime - is this amount of rust OK?

Hi all,

I'm considering buying this 2020 Prius Prime in Montreal. It has an average amount of mileage on it (75000 km, 47000 miles). It is a Toyota certified vehicle, but it shows signs of rust underneath. I haven't viewed it from under a lift, but here are some pictures I was able to take from the back of the car. Looking for advice/opinions on if the level of rust is acceptable and if you would go ahead with the purchase if everything else checked out.

Thanks.
