Best way to build up some cash is get an old banger with atleast 200BHP and go to special events, then do a trak call costadi something or another (second down on the list) and win both events you get a car worth 260,000 Cr. That should sort out the cash problem. So far I've bought myself a S3, RS6, M3GSL SL600, Aston Vanquish,. I wish that was my garage.
