WhoCanFixMyCar reviews the maintenance costs of three popular family cars.

Choosing the right car is about more than the upfront cost - it's also worth considering how much money different aspects of maintenance will set you back. We thought we’d look under the bonnet and see for ourselves, comparing three popular family cars: the A3, Astra and Leon.



Average maintenance costs


The data in this guide is from 2023, and all prices are averages from quotes provided on the WhoCanFixMyCar platform. We selected four maintenance categories for comparison - full and interim service, MOT and aircon regas - and three popular family cars with comparable running costs.

After finding out the average price for each model in these categories, we added them together to determine the total annual cost.

Full service£191.67£193.72£189.69
Interim service£135.09£136.89£134.46

Cheapest overall: Vauxhall Astra

A yellow Astra

According to our data, the cheapest model to maintain is the Vauxhall Astra, with an average annual maintenance cost of £437.49. It might have been around for a long time, but the Astra still keeps up with the best of them, offering great all-around value.

Cheapest for servicing: SEAT Leon

Seat Leon Cupra 2

Despite winning overall, the Astra was beaten in several categories by the SEAT Leon, including servicing. The Leon's total average servicing cost is £324.15 - £2.61 cheaper than the Astra. And this isn't the only area where the Leon reigns supreme; it also has a five-star review from WhatCar?, beating the Astra's three-star rating.

Most expensive for servicing: Audi A3


It's no surprise that Audi's stylish A3 model didn't do particularly well against the Leon and Astra. Affordability isn't the German brand's M.O., but it excels in many other ways. The A3 is the most expensive car for an MOT - by just one penny - and has the highest total servicing costs, coming in at £330.61.
