If I trade in my car, do I still get all the My NRMA member benefits?

You'll only receive the buying benefits. As part of your trade-in, you can apply your My NRMA member benefits code at checkout when buying. However, trade-in customers are not eligible for the $50 cash back or the $100 discount offered to sell-to customers, those rewards apply only when selling your car directly to Carma without purchasing at the same time.
