A few notes:

- there are only very few locations where you can park for free. The cost is varying depending on location (and it might not be expensive compared to NY, but it is quite expensive compared to other big cities). If you are not staying overnight with a friend where you could potentially park for free (basement carparks in condos) you need to consider the cost of parking overnight. Parking fees in a shopping centre at Orchard RD but also in the outskirts can be easily 4 SGD an hour, (Coupon) roadside parking goes usually at 50ct per 15 to 30mins .
- Traffic in peak hours can be quite bad (Sundays are considered peak)
- defensive driving is advised, most drivers won't signal when changing lanes and sudden stopping (Taxis), sudden lane changes, sudden turns are pretty much the standard. I dont agree that drivers here following the rules (and Taxi drivers are the worst) as they dont.
