1. Steal car somewhere on the streets and drive to LSC shop.
2. Start program
3. hit 5 to max mod my car
4. go to theft protect (car should turn golden) and then hit 6 and type elegy.
5. buy Tracker and wait till i get kicked out of the shop with message "This vehicle cannot be moded"
6. Let this moded car stand somewhere and drive to another nearest LSC shop with any other car.
7. Call mechanic and let him delivery moded elegy custom to me.
8. Pick delivered car and drive to LSC, hit 7 to max mod it and sell it.
9. I do like 2-4 cars per day. DONT ABUSE IT TO MUCH.
