'I've been a mechanic for 55 years - I'll never buy a new or used car that's missing one vital feature'

The majority of vehicles that feature a petrol or diesel engine come with a dipstick that can be removed by owners in order to check how much oil is in the sump and whether it needs to be replaced, reports the Express.

However, a growing number of models no longer feature an oil dipstick under the bonnet in order to save money when producing the vehicle and to encourage owners to take the vehicle to a specialist for maintenance and
