Personally if it's just a few days, I might just stick to taking a taxi/grab

Hello Gabriel. If you are driving with small groups of people (2-4) or going solo most of the time, we suggest going for either budget, economy or luxury depending on your taste and driving style. If you are fetching a larger group of people (4 or more) and you want some room and comfort we suggest gong for the SUV or MPV class.

Go to https://www.motorist.sg/car-rental to take a look at the list of cars we have for rental.

I hope you will enjoy your stay with us!
