Fluff and dust work well together.

20 odd years ago I had some wheelie bin liners made to my own spec ..very thick plastic ..some of which I still have left ..cut in half they make a great boot liner ..

Leather seats so they wipe clean easy enough. Use a boot liner and mat, really good quality, impressed with it – I started a thread on these a while back if you’re looking for links

I often borrow a hatchback for bike trips, I stick a big blue tarp inside and the car has never got dirty as a result

I started a thread about this recently for a berlingo. Got boot liner with bumper flap off ebay, was fine but just too small. Cost £15, fits the wives wee car well. Seems “tarp” was a popular and cheap option.

Wanted fancy so priced up the custom ones with all the bells and whistles I wanted but couldn’t spend that much!

Hatchbag £233
Titan £133
Rhino £145
Boot Buddy £175

In the end went for a heavy duty tarp, rubber mats and waterproof seat covers with a bib type thing. Should cover me, or the car for all eventualities. Total cost £60

bike on the roof in a lockable Thule rack, front wheel in a wheel bag, boot lined with thick old blanket that I can chuck wet/muddy gear onto. also have used IKEA bags on road trips for “stuff”

I also have a 70l plastic bucket to drop all the wet stuff, bags and helmets into to stop them rolling about

Shower curtain in the boot. Cheap, waterproof and any colour you want.

Got one for both cars, rubbery material, with a lip and waterproof, neat and tidy, seem to have them to fit most cars, and much cheaper (and better) than manufacturer one in my case (VW).

Im thinking a Tarp cut to size and glued together might work now. Could maybe make a custom bike bag with that if its really dirty.

Mud, lost sweets, all mixed deep into the seats with a generous topping of spilled drinks and the odd vom*

If I was bothered about the interior of my car, I’d just fold up a tarp as appropriate, with some old towels/sheets to protect metal bits from each other.

*actually I think almost all of this has landed on the mud mats in the footwells or been caught in an appropriate container so far.

I use a picnic rug with a waterproof backing.

Doesn’t rustle like a tarp does.

But are they actually waterproof or just water resistant? I used on on the backseats of my last car and put a wet tent ontop. The seats were soaked through when i got home.
