My aftermarket parking sensor installation cost about $2000, broken down as follows: $500 parts, $250 painting, 15 hours labor @ $85. The $6000 number from Tesla is probably $4250 parts (because of new front and rear fascias) and 10 hrs. labor @ $175. The only downside of the aftermarket install is that it does not provide the visual feedback you get with the OEM install, just different audio tones for front and rear sensors.
