Has anybody purchased parts from Grey Thompson?
Something else that sometimes provides scammer evidence: Search the web for images of their parts (or cars) that they've listed. (Google Lens from phone or right click on image - search the web from desktop PC). If you find that exact image on some other site (for example) that's already sold a year ago, BIG red flag!
I've seen Grey Thompson in several of my FB groups & he reeks of scammer.
