If it is your first offense and you knew the people who's car that you took, then you will most likely:
1) get probation for 3-5 years
2) lose your license for 6-12 months,
(depending on state)
3) have to go through an ASAP program for about
1 yr or more($400-500)
4) possibly get a restricted during the suspension
period, provided you go to school or work.
5) Overhead jail time: 10-24 months; if you fuck
during you probation time.
6) might have to do community service as well:
50-250 hours.
If, on the other hand, you have any prior arrests; especially likened to the ones that you have listed above.......well, jail-time, most likely 5-10 years for two felonies. You may possibly get out in 5 due to good behavior. I sincerely hope that this is your first time messing up like this man, b/c if not, you truely are fucked my friend, good luck anyways.
