hi guys, nit sure if this is the right section for this question.

i have an Astra F (mk3) and would like to install some rear parking sensors.

anyone know of any decent ones? it doesnt have to have a fancy screen, i just want one that works very well.

i dont really fancy drilling into my bumper so any "drilless" ones about? or is u better to get one i drill in?

cheers!
