I've just gone through the mats and carpets buying experience, cabin, driver's footwell, passenger footwell, steps, door pockets.
Next steps: 1. Take them all out (maybe keep the VW rubber mats). 2. Stick in bin. 3. Use wet cloth, soap and vacuum cleaner as condition requires. 4. Advise new owners not to stuff their vans with clutter.
My opinion; it's all just poor fitting, tacky (but not particularly tacky double-sided tape), unnecessary clutter.
It might be my fault being a cheapskate and not buying Brandrup especially considering how much the vans cost, but nearly £200 for a bit of synthetic carpet is a bit more than I'm prepared to pay out.
My reasoning goes beyond cost. I think I will try and keep my van minimalist. Avoid clutter that needs to be bought, packed, stowed away and then put somewhere at home. Yes, the van might get dirty, but it's an activity vehicle and with a bit of elbow grease I'm sure it can cleaned up reasonably well. If the seats get so bad they need recovering in the future, so be it, I'll do it when condition requires, perhaps at time of sale when the investment could be worth it.
