They will charge whatever they can.

They charged me for the big investigation test (~£300) alongside with the routine test (~£60). The issue my car had couldn't be fixed by them as said that the parts should be sent to Mercedes and they will give an answer on the issue.
They could find with this big investigation test that my auto light was fault and switches off and on randomly.
Extremely disappointed as I realised that if they will see someone non knowledgeable in cars (a woman for example) they will try to get money from whenever they can.

This garage didn't work for me. Hope no-one else will have to waste their money this way.
