Need help buying my first car

I've just turned 18 recently, and I plan on buying a car at the end of January 2022.

I have about 2k to spend on the car upfront.

I need a reliable car to not break down on the motorway as I'm going to be driving around 10 miles to work and 10 miles back home, 5 day a week. (Around 100 miles a week)

I've been looking at the Peugeot 207 and the Hyundai i10 and i20. I have heard that the 207 isn't very reliable, so was just looking for recommendations.
