Just bought a used Prius with no floor mats. It's raining here so I want to protect the floors from the grime, but I don't want to shell out a whole lot of money. I found these floor mats: They say "all vehicle", but how is the fit on a gen II prius? I know it won't be perfect, but is it decent? There's also no holes for the hooks in the driver's side mat. Do those hooks come out of the floor?
That type is approximately sized and you just trim off portions. If you're going to go that route, I suggest https://shop.advanceautoparts.com/p/economy-black-floor-mat-set-rubber-black-4-pc-505b/10999298-P They're only $8.99 right now. I got these and trimmed them. I just pierced a hole for the pegs to hold them, but their studded backing holds them to the floor pretty well anyway.
You can get the Toyota all-weather front floor mats for about $30. Custom fitted. Then, buy a couple small rectangular non-custom mats for the back from Walmart, Autozone, etc. Here is an online Toyota parts dealer with a decent price. But, you could do a search to get the optimal price... PT9084700W02 - Toyota All-Weather Floor Mats | Evans Toyota, Fort Wayne IN Paul.
