Most people buy floor mats first because floor mats are the obvious thing. Sometimes that is right. Often it is not, and the surface that actually needed protecting gets damaged while the mats sit in a footwell that was coping fine.

The order is not a matter of taste. It follows from three things about how the car is used.

Question 1: How many rows?

This decides most of it. A two-row car concentrates wear in the front footwells. A three-row car spreads it across the whole floor and, more importantly, puts every third-row passenger past the second-row seat backs on the way in.

In a seven-seater the seat backs go first, ahead of everything else. In a two-row car they are usually third.

Question 2: Who sits in the back?

Children and dogs damage the backs of the front seats. Adults mostly damage the floor under their own feet.

This is the question that flips the order in a two-row car. Same body, same size, and a family car and a commuter car want different things first.

Question 3: What goes in the boot?

Shopping does nothing. A boot that carries groceries and a weekend bag will look fine for years.

Luggage, tools, prams, plants and dogs are what ruin a boot floor, and boot carpet is expensive to put right later because it is bonded in and hard to replace piecemeal. If the boot does real work, the liner moves up the list.

The four common answers

The principle underneath

This ranks damage by how permanent it is, not by how visible it is or what each item costs.

A dirty floor mat is a cleaning job. A scuffed seat back is a mark on the trim that stays. Worn boot carpet is a line item on a trade-in valuation. That is why the seat backs keep coming first in cars that carry people in the back, even though mats are the thing everyone buys first.

Two things that do not change the order

Price. The cheapest item is not automatically the sensible starting point. Buying the wrong thing first just means the right surface was unprotected for longer.

Season. There is a habit of buying mats before winter and thinking about the rest later. Winter changes what lands on the floor, not which surface is being permanently damaged.
