My '34 Mercedes-Benz 500 K Roadster   
 
  I Built mine from a kit, which was a full scale model weighing 
over 2 tons (4,000 lbs). Wish now that I had not sold that car 
at a special auto auction for a little more than $20,000. 
About broke even on what the kit, extra parts and buying a 
used '70 Camero for $1,000 cost me. Had to use the front 
frame, rear end, engine, transmission & some other parts.
 
Starting
 Friday, more than $200 million' worth of classic and rare automobiles 
will go under the hammer at the auctions surrounding the Pebble Beach 
Concours d'Elegance in California, with more than 70 of those expected 
to 
fetch at least $1 million. Even amid a booming market for old cars, 
there are 
a few that stand out -- including one that was once ditched on
 the side of a 
California freeway, and another that sat in a shed for 
nearly 40 years which 
could break the auction record of $16.4 million.
While the Pebble Beach show itself will draw
 15,000 visitors on Sunday, 
the plethora of auctions around the event in
 Monterey, Calif., have become 
even more of a spectator event. Among the
 gawkers will be wealthy buyers 
hunting not just a jalopy they can boast
 about, but a place to invest their 
money that could pay off big. 
Hagarty's Insurance, which tracks collector-car 
prices, says its index 
of "blue-chip" collector vehicles has risen 9 percent this 
year
 to a record high -- a greater return than almost any other investment 
class. The world will always have more gold and stocks, but there won't 
be 
any more 1965 Ferrari's.
From the hundreds of vehicles that will be 
offered this weekend, here's six 
that will get much of the attention and
 some of the highest bids:
1936 Mercedes-Benz 540 K Special Roadster
The star of the weekend, this massive, 
supercharged Mercedes-Benz was 
owned by Baroness Gisela von Krieger, one
 of the last members of German 
aristocracy and a socialite once named 
among the world's most beautiful in 
pre-war Paris. After the war, a 
newly reclusive von Krieger moved to New 
York, and later Connecticut, 
bringing her car with her. When her brother 
died in Europe in 1959, von 
Krieger stayed, leaving her car in the shed of 
a Connecticut inn for 
safekeeping.
This 
isn't just any Mercedes-Benz roadster, but one of a handful of copies 
of
 the finest cars the company built before World War II; the von Kriegers 
ordered it with a custom body, dash and even a pushbutton radio, a 
rarity 
in the era. Despite entreaties from several collectors and 
Mercedes-Benz 
itself, von Krieger died in 1989 without ever selling the 
car, despite not 
seeing it for more than three decades.
With no heirs, von Krieger's car fell into a
 legal abyss; only when a lawyer 
contacted auctioneer David Gooding in 
1991 about an "old, black two-seat 
Mercedes" did the mystery start to 
unfold. With a few more details, 
Gooding flew across the country to 
inspect it, and found the Roadster 
almost as von Krieger had parked it 
in the '50s -- her spent cigarettes still 
in the ashtray.
After a spare-no-expense restoration by 
owner Lee Harrington, the 540 K 
Special has won several prizes over the 
past few years, including a 
best-in-class at Pebble Beach. Estimates put
 the car's value at a minimum 
of $10 million -- and given the passion 
for having one of the rarest 
vehicles in the world, it could sell for 
far more.
