Hey!
Bad Martin! 
I learnt somethin which i found very useful... Coz in learnin,
awaes got poles as guidelines mah... Come to outside, no
poles..
mY inst taught me tis.. For left side parkin, the pt to use is, the
car headlight, the one beside the lot u want go in, reach the
triangle area of ur car, then full lock go in liao lor... U slant
the car abit when going in, easier...
Then see see side mirror, make sure don hit anythin lor...
If rite side, same as direction change...
no cars, as guidelines, eh... got to ownself judge liao.. tis i by
luck by luck go in only... hehee
