As Sirebel said, take your time, figure out what your objectives are, as well. If you're going for 100% completion, you need to be astute in your purchases.

Also, if you've yet to make IAPs, don't, as you'll reduce your daily free Gold through video ads. Also, if you're going for 100% completion, always buy the Ferraris at showcase price, don't wait for a sale.
