Welcome! You WILL enjoy this car, trust me. Few things to check for since it's brand spanking new:
Shipping issues:
1) Check to see the tires are inflated to the correct pressure. They pump them up for the boat and train ride.
2) Some dealers have failed to take the spring spacers out of the springs once the car is delivered!
3) RAIL DUST. Once car is clean, brush your fingers (backside) gently over the hood, roof, etc. If it's rough, you very well may have raildust from the train. The only solution is to have the car clayed....something the dealer shoud pay for.
Stereo options:
1) A lot of people perfer to have the DDL setting on the car shut "off." Do a search on here or read the owners manual to see how to do this.
2) The stereo output can be boosted by up'ing the gain on the amp in the trunk. Again, a search should help you out.
Have fun and burn some rubber.
