Cars do not like sitting unused for great lengths of time. Batteries lose charge, brakes start to seize, electric motors begin to stick, fluids begin to break down… the amount of time it takes for these things to happen can vary but it’s important to understand that your car needs regular use.

It’s been 10 months since we last put pen to paper to report on the current state of the classic Mercedes Market, although those short months have flown by! After a busy summer of car shows, car sales and conversations, it seems once again that the Autumn has snuck up on us out of nowhere.

With thousands of individual components, some of which were bespoke to the model, there will always be a point in your classic car ownership journey where you may find it difficult to diagnose an issue or replace a failed component.

Those of you who have followed our journey from a small hobby business (or side hustle as it is now called) to the 60-strong, internationally renowned team we now are, will know that Bulkheads have been central to the growth of our business.
