Got any more? I'm a photographer and a nerd.. so..yah
I would say, perhaps some window tint?
If you haven't done any engine mods, you might consider chipping the engine, it would add a LOT of hp and torque. About $500 will take the car from 150hp to over 200 with a simple ECU flash. You might also consider updating the intake, and the diverter valve to better support that upgrade.
I'm *assuming* that your silver Beetle is a turbo?
