Just had a nightmare at my local arc car wash. Used to use it weekly in my corsa d and never had any problems at all. Just taken my adam slam through it and emerged the other end minus one wing mirror carbon fibre bit, no sticker on the driver side and a massive kerb mark on the driver side alloy. Had a big argument with the company but it does state that cars are taken in at the owners risk.
