A search has found very few comments re either of these Miele appliances.
We are replacing cooktop, wall oven, microwave, and dishwasher in the next month. After our first visit to an appliance store, we were about to purchase a Bosch cooktop and wall oven... but owner comments in several places re both use and service have us continuing to search.
The Miele gas cooktop is about $400 more than the Bosch we priced but less than an equivalent Wolf, which was at the top of our price range. So if comments on that were comparable to those re Miele dishwashers re reliability and service, we'd be interested.
The Miele wall oven at about $3,200 is much more than the $1250 for the Bosch HBL3350UC we viewed and priced but if comments are strong, we'd consider that as well. (We are also seriously considering the Miele Classic dishwaster as relatively good value for money in this range.)
Any comments from people who own the cooktop and/or the wall oven are appreciated.
