Listen, PD never rewards you for not working for something, so if you want something, your going to have to work for it. Simply put, there is no easy way of getting the X2010, really. Even grinding B-Spec to level 35 takes time and most of the time requires you to sit there and be extremely bored because you only have 5 minute races up until Extreme events.
It's really not worth the wait unless you have a wheel. Driving with the DS3 is absolute hell until you sit there for hours trying to perfect it. Even then it's still bad. Save your money and buy an FGT or Ferrari F1's (be warned: You can't use them unless it's a Ferrari event or the room host online has specifically selected Ferrari F1's).
