Generally, we will always suggest that you have repairs undertaken by the supplying dealer. This is because it is generally quicker, and the dealer will be able to arrange and pay for repairs without added complications.
If you and the supplying dealership are a significant distance apart, or if the relationship between the two parties has broken down, or the dealer is unable to arrange repairs, we will consider all requests for independent repairs, but this is not usually at a franchised dealership because their labour costs are far more expensive, and for a used vehicle you are not necessarily entitled to new manufacturer branded parts. This is classed as "betterment", and you are only entitled to be put back into the position you would have been in, not an improved position.
It is recommended to obtain three quotes to ensure that the price quoted is a fair one, and that the work assessed to be carried out is correctly diagnosed.
