We have been looking to buy a 2-3 year old Mercedes A170SE auto for £10,000 - £13,000. As we want a light coloured interior and they are as rare as hen's teeth we have been offered a brand new A180 elegance SE auto with Parktronic pack and folding mirrors by a Mercedes dealer for £17,450, which they can do by registering it first to themselves and then to us. List is over £21,000. Should we go outside our comfort zone for this or carry on looking for the used one? We only do 3,000 – 5,000 miles a year and would keep it for a long time.
