Buying outside of eBay via Wire 116610LV

[Jlk33]

Hi All,
As I write this, it feels more suspect in writing than in my head. Long story short - fair priced 116610LV on eBay. Messaged seller a few times on eBay, then contacted them through their site.

Seller offered a significant discount to pay via wire off eBay. Which could make sense because of fees, but also raises some red flags. Seller is unwilling to budge on eBay price, but immediately knocked off 1,900 via wire.

Their feedback is flawless on eBay, Chrono24, and Google. The seller appears to be an independent dealer, not affiliated with any physical space, stores, or a larger company.

They said they could provide references via What's App chat, but that doesn't feel so legit.

Do I just eat the additional fees to get the platform protection of eBay or Chrono24?

Thanks in advance.
