The few carparks i will try to avoid are,
1) Bukit Batok, dunno which area but I remember there's a
mac and foodcourt beside. I went there once, and scratched my car.
VERY narrow.
2) Liang Court, narrow and spiraling. Will be challenging for
new drivers.
3) Opp Cineleisure, open air carpark. Definitely will avoid
there. Unless you want birds to drop gold on your car.
Will add on if I can think of more.
