7 day return period for new car... What to do with it?!

[HyggeAndKisses5]

DH and I just bought a new (used!) Audi A1 from a local dealership and they had an offer on where you could return the car in 7 days no questions asked if you didn't like it for whatever reason. We were looking for a second car as we're expecting.

I'm just wondering what to do during the next 7 (well 6 now) days to really test the car and see if its a good fit. Want to make sure I've made the right decision as it was quite a big purchase! So far I've just driven the car to drop DD off at school and go to the supermarket.

Motorway
Country road
Shopping trip
Work commute (if applicable)
Parking in different spaces
Fill the car up for a trip you'd do and see how well it handles the weight
Try get out in the rain and at night

A shopping trip is a must! The important thing is to try a get a feel of the car. So maybe try and drive different weather conditions.
Make sure the car is smooth and comfortable to drive. Try higher speeds as the feel of cars can change dramatically on motorways.
Also make sure you test your car to see if it has all the gadgets you need and what features and add-ons are available. It's best to check if everything is in order.
