Nooo don't get cheap ebay mats! I bought some off ebay for my old car and they were really bad quality. The drivers mat wore out after a few months! It's much better to pay the extra and get some from a dealer. Plus dealer ones will have the retaining clips to stop them moving about.
nah the ones i got were great, they are from a guy who worked in a seat dealership, they had retaining clips and were cut ot fit the ibiza.
