i currently own a vr v6 auto that hasnt had a tow bar fitted and wont to put a tow bar on so i rang a shop near me and he quoted me 400 - 500 bucks nd im like yeah mate thanks, but can i put a tow bar onto my car with drilling the holes myself or dose a shop need to do it?
so pretty much 20 bucks for heap of good drill bits a tow bar and bolts
but with the bolts i might use the standard ones but for extra peace of mind i might pay the bit extra and get new ones somewhere.
so like less than a 100 bucks and couple of hours work LOL
