How do we know these are official OEM parts resellers? Anyone can start a website and name it to sound real and convincing. This is the big problem with online sales.
There are dealership parts departments that sell online. Those would be more trustworthy. It’s a minefield out there. Trust but verify.
Tasca is a dealership chain with a large online presence. Not sure about GMpartsdirect, but probably the same. Usually you can find some contact info on the site that will tell you what dealer runs it. There are companies that offer ready made websites for dealers to sell parts through, they just have to pick a domain name that will get a lot of clicks. JimBobBuickGMC.com might not, but Gmpartssuperstore.com or whatever will.
Dealers are unlikely to get into counterfeit parts. GM tracks our "loyalty" and it impacts what we can return to them. They know where we buy things from. It's not worth it on so many levels for a regular franchised dealership to do sketchy things. Weird companies supposedly from the Midwest that cold call and tell me they will sell me large quantities of heavily discounted items in GM packaging get told off real quick.
To my knowledge, I've yet to encounter a truly counterfeit part. I can totally see it buying something like spark plugs at a too good to be true price from a basically unknown seller, but it's like if you went to a sketchy place to buy designer shoes or something. At some point there should be some red flags that the seller can't be trusted.
I buy parts off eBay all the time, the Silk Road of BITOG. Most of them used, some new but from sellers who figured out a niche and bought a ton of an item, for example the guy who sells hundreds of 1990s Explorer antenna trim caps. Nobody is faking that, if they are, mine fit fine and came in impeccably reproduced Ford packaging. eBay is not where I go to buy spark plugs, especially at impossibly cheap prices. Buyer beware and all that.
