As a city dweller, you may want to check if the city authorities have any restrictions planned regarding cars. No point in getting a petrol car if they are banning them from city centres etc.
Its just another tick box you have to do, try and find out what lies 3 years ahead.
Good luck with your search there are many cars that exceed bmw in terms of build quality, tech, and lower prices.
Just create a shortlist and give each a thorough test drive.
