I am planning my new kitchen and will be having a built under single oven. At the moment I have a neff single cavity which is 12 years old and not cooking well. Is it worth spending more ££ on a Miele? I hear they are very good. Also, the capacity seems bigger. Neff is around 65 litres and Miele are 74 litres. Not sure how much difference that actually makes though. All oven related advice greatly appreciated.
