Real Source is located about two hours from me.  They are a pretty good
company and got into VW stuff about 5-6 years ago.  As Ron says, they started with
Corvette parts and have a very popular two day Corvette show on their grounds
every year.  When they started with VW parts, they also did the two day show
for VWs.  Entrance fees and food were free if you drove a VW.  Over 400 cars
attended last year, including my '91 Carat.  Last year they added a swap meet
during the show and this year, they will have a separate swap meet in April.
This is a big deal for us VW and Vanagon-starved Midwesterners.  By the way,
they also bought P. B. Tweeks, the Porsche after-market parts outfit from Indy a
year or so ago.  And they have a two day Porsche show too.  Effingham, IL,
their home town, is at the intersection of I70 and I57, good location.  Its fun
to go to the VW show and get into town and see VWs, old and new, coming from
all directions.
