Mine are a toss-up between the Miata front BBK and the M3 headlights.
The BBK came with wrong parts, sketchy instructions and stainless flex lines with E36 M3ty adapters.It is a big name kit that I bought through a trusted reseller. The reseller was great and acted as a mediator. I ended up buying a set of the reseller's flex lines to finish the install.
The headlights were a clearance buy and didn't reveal that the kit was for an M3 coupe. I had to buy another set of corner lights for a sedan. The kit came with an extra wiring harness but no instructions on how to hook it up. The reseller was no help and barely communicated with me at all. Funny thing is, they have no problem sending me almost daily sale items even after I've told them I won't buy from them again and why.
If you want to know the manufacturers or resellers, send me a PM. I won't name them here.
So, what recent purchases are you disappointed with?
