Here is what I have found out through a little searching. OE connect actually owns the trade mark from mypricelink. They were awarded it in may of this year. There will be around 7000-9000 part numbers included and it will only be what they call collision parts. To get a list price you will have to go through the my price link tab in OE or possibly the website. I have heard a couple times OCT 1st will be the start.
Now the interesting part..... everything that you sell wholesale to a body shop with go through collision link. The body shops estimate software will submit the entire quote to collision link. Then collision link/mypricelink will look at age, location, aftermarket availability, etc and price to come up with a list price. From my understanding will beat aftermarket list and then the parts that have a patent on them will be more in line with a normal list price or jacked up. All of this is supposed to happen in seconds. A couple articles I have read quote someone from GM stating that the process will require no extra steps from the body shop but will require a little more work from the dealer.
What i don't know
What the allowed mark up will be on parts that are matched with aftermarket pricing? I have a feeling it will be like bump the competition.
Will we still have bump funds?
How Much work will be involved from the dealer?
If GM is able to match the aftermarket and pretty much double their share in the collision market can they keep up with the demand?
Like I said all of this is just from searching around nothing official
