Make sure you know your needs before getting a OPC
I own a OPC myself.
As i use it when i go out during the nite and weekends.
And my company don't pay for my parking as well as petrol, an opc
serve me ok.
But sometimes seeing the car paring there during the day and can't
touch it without using that $20 coupon....... irony to think that
you own a car without getting to use it then.
