to be honest I haven't really had time to make more improvements to my car, consumption this year lingered around 3.8 liters/100 km. in a very wet and chilly summer and even included driving lessons for my wife.
I also stumbled upon a 'new project', I saw it as a great opportunity to make an old dream come true: owning my own RV. the interior layout was perfect, the base, body and engine too. The low price and honest seller were the deciding factors.
