Ha! Our clown house was custom built in about 2006. (Don't worry, not for us. We bought it on a short sale and DH walks to work.)
First thing to go, at about 7 years, was the 36" Dacor stove/oven. DH fixed it, but he literally had to do stuff that wasn't even in the manual to fix it. About $350 in parts. We're told it was a $10k appliance, which is somewhat totally unbelievable. The following year, the built-in Kitchenaid microwave that is tucked into an upper cabinet went kaput. Discontinued, parts not available. Replacement cost? $1500. Are you serious? DH found a place that specializes in buying up discontinued appliances. We got the same one, new in box, for "only" $600, an hour's drive away. At least it matches the rest of the appliances, so there's that.
Oh, and the seller took the refrigerator with him. Yup, the special snowflake cabinet depth model, which was tucked nicely into its own custom cabinet. The only one that fit was $3k. We did a lot of surfing and found it from a dealer on the other coast for $2600. It doesnt have much in the way of bells and whistles, either.
Crazy.
