After reaching Face level 10 you will be granted a DAI LO 40% discount when you purchase cars and clothes. There are also clothes that grant about a 15% bounce discount for vehicles but they may not stack with the Face level 10 discount. There are four vehicle stores you need to purchase from, two in North Point, one in Kennedy Town, and one in Central. About $3.5 million total will be required for the purchases.
