I have had good service from almost every vendor in the rebuild of my 70 Charger. I have almost $27,000 in this car and that includes about $3000 in bodywork and paint supplies. Interior parts from Year One, engine parts from Summit racing, Axle parts from Moser. Suspension and steering from Just Suspension and Firm Feel. Headers by TTI. In each case a defective part was immediately met with a reasonable return policy. One time Year One actually paid for return shipping of a fuel line that I ordered in error. Most of the time that I have had poor service is with LOCAL parts guys.
CUSTOMER: "Hello, I'd like to return this widget, it didn't fit right."
PARTS GUY: " Waddaya mean? Whats wrong with it? Did you drop it or something?"
This sort of thing is maddening. YES, there are often stupid customers out there, but instead of first assuming that the customer is an idiot, why not the following:
CUSTOMER FRIENDLY PARTS GUY THAT CARES: " Didn't fit? Oh, sorry about that. I'll get another and compare it to this one. If it looks the same, maybe the problem is on your end. Lets take a look.."
How hard is that?
