Instead of going to find the car. Go to any chop shop activity and add a car to your hud. Use the cheat code that will add the car to your garage. Also instead of going to your crib then to rim jobs if modifications are need. Go to the nearest rim jobs and enter the office. Pick the car needed from your garage then enter the rim job garage. Get into the car and take it back to the chop shop. This is good especially if the car needs modifications your already at rim jobs and can modify the car. Keep doing this to beat the chop shop activitys.
