As most warranties are very similar in their wording you will find that whilst the dealer is responsible to replace or repair any defective item that is covered by warranty, they are not responsible for the travel cost or time in the van having to be returned to them for any such work to be done.
When you think about it it is really quite reasonable as they do not have much , if any, control as to where the van is taken after the sale, and as we all know, some folk wil travel miles to get a better deal, failing to take inot account the exact situation as described,,,,,,,the cost of return for warranty work or servicing.
