Mercedes-Benz cars are legendary for their engineering, but not all models are created equal when it comes to at-home maintenance. If you’re a DIY enthusiast looking to save money and enjoy the satisfaction of working on your own car, some Mercedes models are much friendlier than others. Let’s break down seven popular Mercedes—from the easiest and most affordable to the most complex and expensive—so you can choose the right project for your garage.
And remember, no matter which model you own, a Mercedes workshop manual or PDF workshop manual is your best friend for tackling repairs and keeping your investment in top shape.
