I don't normally buy from an ad. I see what's in stock. Coincidentally, everything in stock always seems to have VIN etching which is completely useless to me. If someone steals parts, that's an insurance issue, not a me issue. I don't think insurance gives me a discount for VIN etching so obviously they believe its value is close to zero as well.It's funny but you have the power in your hand. All you have to do is say the word OMVIC when dealing with these charges. But if you walk into a dealership that has already rustproofed a vehicle before the sale.....just walk back out. Make sure you see pricing online first and they have to honour that....pretty simple. If they introduce anything into the deal afterwards it is going to be a problem. IF they advertise the unit with those features....then you don't walk through the door.
