When it comes to car repair and maintenance you need to shop around to get the best price. Prices for the same job can vary drastically from garage to garage, so it is always worth obtaining a few different quotes before you decide who to go with.
Main dealers often charge a lot more for parts as well as their labour rate so the overall price is usually higher, but you may find that you need to go to the main dealer if the vehicle is still under a warranty for example.
When comparing prices be sure to find out if they are using genuine parts or non-genuine and weight up the options carefully. You may also find that if you need a repair carried out quickly then you may have to pay a little extra for fast delivery of clothes etc.
Do not be afraid to ask for a breakdown of a quotation for repairs of your vehicle and never give a garage free reins by telling them to go ahead with any work without first telling you how much it is going to cost as this can end is a nasty surprise.
