Hi guys, hopefully you can help. Lease company trying to push me to use main dealership (double/treble the cost of others) New lease car, due first 'Service A' at 10k. -Contract says "The vehicle must be maintained in accordance with Mercedes Benz published service intervals within the Official Workshop network". -Mercedes online chat said "As long as genuine Mercedes parts are used, you're ok". -Google said "Block Exemptions Regulations 2003 means they can't force you to use main dealer" link here. -Lease company won't answer any direct questions, just keep repeating "You have to get it done at main dealership". Where do I legally stand with this please?
