Purchase advice

Hello, I’m looking for a small car, where a flat loading area (adjustable floor) results when you flip the back bench. The Honda Jazz is eliminated, because it is probably very rusty. My criteria next to the trunk are:Maximum 50,000 km, maximum EUR 12,000 (regrettably less), as low consumption as possible, starting from 90hp (less only if he still pulls the “wurst off the bread”. Favourites are Fiesta and Polo. From which year of construction the Fiesta has the Luggage compartment? Are other brands recommended (repair vulnerability and costs) ? Dacia has too long waiting times, I don’t find any needed.
