Having recently had the sill repaired due to an altercation with the kerb (had both sills done at the front too due to rust at the same time), I've now noticed the offside arch is bubbling! Phoned up the dealer we bought it from as approved used, and they are sending someone to our house to assess it this week, don't even need to take it to them. Impressed by this, lets just hope they agree it needs fixing.......
