Dont waste money with car ownership in Singapore.
Instead, you use all these monies you saved from car ownership and pay for premium location of your homes (either HDB or condo) within 100m of an MRT station. The prices of such properties will increase or at worse maintain its value over time.
At least you know that these monies you used for home ownership will maintain its value or even give you some capital appreciation instead of outright depreciation in car ownership.
