Yep. If you phone me at work it depends on work load and mood to see if I'll humour you looking up parts without VIN. Hyundai's Microcat makes you start over when you do put in a VIN... So, say you went through a half dozen to a dozen menus looking for something, there is no shortcut back when you do put the VIN in. Much easier to start with a VIN. Same software as Ford.
Doesn't need the whole VIN, most don't
Hyundai- last 8 digits
Ford last 8 digits
Chrysler last 9 digits
M-Benz I think was last 6 or 8, but had to be looked up in separate software.
Some like Acura & Mazda need the whole thing. A thick accent or a bad cell phone and it's 50% of the conversation to get it right. A right PITA.
When I order Jobber parts I usually look it up on two jober parts look up suites (Rockauto and a local one) I make a call, so I can advisethe local guys what is most likely to work. Brakes on Escapes, Caravans and f150's are nightmares.
Put it another way, our dealer flat rate techs are over $2/minute, and its not unusual to have 4 waiting for parts. That's $16 for every two minutes of my time.
If you phone me I feel under no obligation to humour your not having a VIN. How would you like it if your wife/MIL/BIL was paying shop rate for repairs on their car and your call about your project held up the repairs?
Call back when it's slow? dream on. There is no slow period. If there is even one slow period, once, someone gets laid off.
Reading some of you, I just shake my head. Must be nice living in the 60's and 70's technological and business climate.
