You should have some cars because you can re-download the DLC you've purchased. I'll start sending cars when online. Need anything special, just ask...
Good point Charlie, you should get one ticket for each of the DLC / Special-Ed gift cars you might have picked up over the years (Camaro Edge Special, stealth GT500 cars, etc) once they've been re-downloaded and installed.
To get some quick cash don't forget about the older Seasonal Events, those 400PP / 500PP / 600PP ones are a good place to start. You can beat the 400PP ones really easy with a mostly stock 20k "starter car", also I'll get a selection of cars up on my shared list tomorrow that should do good for some of them.
Also, ditto what Charlie said about the sending of cars!
