If you foresee yourself getting tired of your 300e then it is probably not worth the expense to maintan. If you were to compare the cost of maintaining the 300e to the cost of purchasing another vehicle and the inevitable repairs that will come with the other vehicle you can make a decision based on the comparative cost.

MB provides a secure path for maintenance, and if I remember correctly they routinely make parts for about 20 years after a production line ends, and frequently for much longer. So if you find value in the car, MB offers the equipment to keep it running for many years to come. IMO there is no car more suitable for enjoyable long term ownership than the 300e
