We see cheap car services advertised all over the place, in reality there are lots of different services - so check what you get for your money.
One of our customers picked up his new car from the car dealer and they said it would have a service. He said there was nothing in the book and the dealer explained it was a "visual" service - basically they looked at things! A cheap service can mean as little as an oil change.
Your engine will appreciate that but there are many moving parts that could all do with some lubrication - a full proper service will help your car perform better - for longer
If you are looking to book a service for your car then you should give yourself a little nudge to question what value you are getting and not just the price. At the end of the day you don't want to pay £50 just for a bucket of oil!
