...power engine still works

I bought this professional-like based on Viking range quality, as a chef I had worked with the brand- I personally like Wolf-and a review I'd read in Appliance advisor's newsletter.
The engine works great, strong enough to mix frozen ice cream-I use to make it- It was designed like a 50s machine, and sometimes the power is so strong that makes the head of the mixer tremble, this is build in a two pieces structure and is so big that has wheels in the base of the machine in order to slide it more easyly.
After one year of use, I just can tell this machine was built with poor quality, some pieces are broke or missing, power knob jumps out of it's place, whisk attachment loosed a wire and almost jump into my face-a wire made out of stainless steel broke, still in use- $65 to replace-, and a mistery piece under the head of the mixer, made out of plastic, broke in pieces.
Trying to find replacemts is a hard work, you just dont find them even in your city(LA), has to be order by mail.
Attachments are standard in other brands here are quite expensive and, has to be order by mail. Customer service could be a nigthmare.
The place for the mixing bowl cames with a cheap plastic bottom, and has to be twist to put in place, that is hard to handle when you has to take it out to pour something like hot caramel.
but after all, power engine still working great.....

even there is a steel plate with the ViKING name on it.....it jumps out, eventually
