You must be aware of the feature of seat warmers in your car. Now imagine how great it would be if there was a neck warmer in a car too. It’s like you could get relaxed as well as drive the car. Well no worries the wish is granted by BMW. Not all the models give you pleasure of relaxation but some like 4 Series Convertible. They are available with different heat settings and integrated, independently-controlled air outputs. Not just BMW, even Mercedes Benz offer you neck warmers. The designers of the company said, “they are designed to extend the so-called ‘convertible season’ beyond the summer months.” So now relaxing while driving is easy.
