Family: multiple vehicles

One car is manageable. Two is where most people's mental system starts to break down.

TL;DR

Once a household has two or more cars, mismatched MOT anniversaries, service intervals, and renewal months make a mental tracking system unreliable. A spreadsheet only half-solves it, since it doesn’t remind you: you still have to remember to open it. What actually works is a system built for multiple vehicles from the start, with a separate reminder timeline per car.

One car is manageable. Two is where most people’s system, a mental note, a sticky note, a vague sense that “it’s due soon”, starts to break down. Add a teenager’s first car or a work van into the mix and it’s genuinely hard to keep straight.

## The usual failure points

- Different MOT anniversaries for each car
- Different service intervals depending on age and mileage
- Insurance and tax renewals landing in different months
- No single record if one car is sold and a new one takes its place

## Why a spreadsheet only half-works

It works right up until nobody updates it. A spreadsheet doesn’t remind you: you have to remember to open it, which is the exact problem you were trying to solve in the first place.

## What actually helps

A system that’s built for more than one vehicle from the start, rather than a single-car tracker you’re duct-taping a second entry onto. That means:

- Separate reminder timelines per vehicle, not one blended list
- The ability to archive a car once it’s sold, without losing its history
- One login the whole household can rely on, instead of one person carrying it all in their head

## Worth doing once, not every year

The setup cost, logging each car’s registration, current mileage, and last known service date, takes a few minutes per vehicle. After that, it runs itself.
