Why You Should Always Check a Car Before Viewing It

The rule is simple: Never drive to see a car without checking it first. A 30-second check can save you a 2-hour round trip, or worse, thousands of pounds on a car with hidden problems.

What Most Buyers Get Wrong

Most people find a car on Autotrader or Facebook Marketplace, like the photos, check the price seems reasonable, and arrange to view it. They run a car check afterwards, if at all. This is backwards.

By the time you have driven an hour to see a car, you are emotionally invested. You have spent time and fuel. The seller is standing there. Psychologically, you are already leaning towards buying. If a car check reveals a problem at that point, you are more likely to rationalise it away.

Checking before viewing removes that bias entirely. You make a data-driven decision about whether the car is even worth your time.

What to Check Before You Go

1. MOT History (free)

CarCostCheck shows every MOT test back to 2005, with advisories explained in plain English and estimated repair costs. If the car has recurring brake issues, a pattern of electrical faults, or structural advisories, you know before you leave the house.

2. Mileage Verification (free)

We plot every odometer reading from every MOT test. If the mileage drops between tests, or if there are suspicious gaps, we flag it as a clocking risk. About 1 in 16 used cars has a mileage discrepancy.

3. Reliability Score (free)

A score from 0 to 100 based on MOT pass rate, advisory trends, and maintenance patterns. Anything below 50 means significant concerns. This is unique to CarCostCheck.

4. Running Costs (free)

Estimated annual costs including fuel, road tax, insurance, MOT, and predicted repairs. If the running costs are higher than you expected, better to know now than after you have bought the car.

5. Common Faults (free)

Known issues for that specific make, model, and year. This gives you a checklist of things to look for during the viewing. If you know the Nissan Qashqai 2014-2017 is prone to CVT gearbox issues, you can specifically test for that.

6. Stolen and Finance Check (£4.99)

If you are serious about buying, the premium check confirms the car is not stolen, has no outstanding finance, and has not been written off. At £4.99, it costs less than the fuel to drive and see a car that turns out to have £8,000 of HP debt on it.

The Smart Buyer Workflow

1. Find a car online (Autotrader, Facebook, Gumtree, dealer website)
2. Run the free CarCostCheck in 10 seconds
3. Review the health score and red flags. Below 50? Move on. Mileage anomaly? Move on.
4. Check common faults and note what to look for during the viewing
5. Run the £4.99 premium check if everything looks good
6. Only then arrange to view. You arrive informed, with a checklist, and confidence that the car is worth your time.

This workflow takes 2 minutes and costs £4.99. It could save you from buying a car with hidden damage, outstanding finance, or a maintenance history that guarantees expensive repairs.

Real Examples of What Pre-Viewing Checks Catch

• A 2018 BMW X4 with a clean exterior but 7 MOT advisories in the last 2 years, trending towards expensive suspension and brake work
• A 2016 Audi A1 with mileage that dropped between two consecutive MOT tests, a strong indicator of clocking
• A 2023 Ford Kuga with a perfect MOT history but £12,000 in PCP finance still outstanding

All three would have cost the buyer time and money if they had driven to see them first. All three were caught in under a minute with a CarCostCheck report.
