If you need work doing on your car and it is immobile or you need to still travel to and from work then you may want to use a mobile mechanic. Their labour fees are often less than a main garage but you may be charged for travel.
Mobile mechanics will come to your place of work to carry out small jobs that can be done on a carpark for example, or may be able to sort out a temporary solution to get the car mobile enough to move it to a new location.
Some mobile mechanics will even take your car for an Mot for you and delivery it back and this can save you money as you will not have to have time off work.
When using a mobile mechanic, try and find one with a really good reputation and one that you can contact easily after any work has been done in case you have a problem.
