I would highly agree with Dennis that in order to actually have your
Vanagon ownership be as painless as possible (it will have plenty of pain
don't worry), you should enlist
a parts expert to help you get the correct parts you need. It is kind of
like using a travel agent versus just doing it yourself online except in
the case of the Vanagon parts
you really aren't spending more. I would love to be your parts expert that
has been selling parts for these vans for 20 years and installing them
myself. A local store, from my experience,
unless it is GoWesty or Van-Cafe where you live nearby and can walk in,
won't really know enough because they don't deal with Vanagons all the
time. Yes, you may luck out
and get an old retired mechanic that knows about stuff in general, and they
can be very knowledgeable. However for the most part, if you are going
into an Auto Zone or Advanced Auto
and expecting expert advice, I think you are going to be disappointed.
They are young folks who know less than you, look your parts up on a
computer and then order them. You can do that yourself online so why even
bother going there. If you need advice and help, our email and even chat
on our site is open 24-7. I try to respond in a very timely manner. We
also have a bunch of articles on our site that you can look at in the
middle of the night if you are up and I am asleep. Not to mention our
Youtube channel.
My advice is to let Van-Again or someone very much like it be your go to
place for parts and advice. You will have much better outcomes than your
local parts store for the most part.
If you haven't checked us out in a while here is our website.
