What statistics support Carolyn Scott's views on DIY car maintenance versus professional servicing?

Based on the content I have, it's mentioned that around 70% of vehicle owners prefer to perform at least some maintenance and repairs themselves. However, the articles also highlight several reasons why professional servicing might be a better choice. For instance, DIY repairs could void warranties, there's a risk of causing more damage, and not everyone has the right tools for every repair. Additionally, vehicle repairs can be time-consuming and might not keep your vehicle in optimal condition. While these aren't direct statistics, they do provide some context to the discussion.
