A friend of mine is interested in a second hand car but has a long visible key scratch (I'm guessing was inflicted by someone else). She has test driven the car runs smoothly and has been passed as road worthy. Would you get the car?
Is there a risk that some deeper parts of the scratch would rust underneath?
If that is the case, should she request the owner of the car to send it in for panel beating/spray painting or negotiate a reduced price to cover for doing the paint job at her own nominated mechanic.
All depends on the price! The key scratch can be fixed quite easily and you can even DIY with products from Autobahn or Super Cheap. If you can save a big fistful of $$ because of the scratch (everything else being A1) then you've done well. Rust is usually not a problem with modern cars in the same way as it used to be with Japanese cars a few decades ago……..
