I bought my car mats yesterday from http://www.vauxhall-accessories.com. I was told by my dealer the Adams don't come with them. So I ordered them ready for when I get him. Use the Facebook 10% off code. Take about £4-5 off. Plus it's free delivery.
They don't come in any new car! You nearly always have to get them a lot of salesmen will throw them in especially when people ask for them on top of there deal! I'm getting a carpet set and rubber set for free!
