Marc-- The yellow car that's #28 on your registry nor the gray Speedster were likely produced by Gemballa, IMHO. I personally called on the yellow 993 when it was on eBay years ago; convenient curiosity as I happened to be visiting near where it was for sale. I also asked Heinz @ Gemballa North America; he said they never sold or installed Extremo parts on this car.

There are at least 4 forum threads about this car. Start your RL research with this one: "FS: 800HP 993 Turbo Gemballa Speedster."

From a 2006 ad:
When it was for sale in Brooklyn, New Jersey by Eddie (seller "carselite") in 2009, as "Porsche 993 3.6 twinturbo Gemballa" item #110354719801; VIN WP0CA2994VS341677:

 

Then for sale in Michigan by Frank (seller "shoda$") in 2012 as "Porsche 993/911 Gemballa Wide Body Roadster," item #130757192025; VIN WP0CA2994VS341677:

 

It is possible that its final resting place is this current eBay ad: "Porsche 911 993 Gemballa Extremo Avalanche parts RARE!!!!!" by seller xtrememotorcars, item #181132489642.

 

The gray turbo has at least two RL threads:
aribop's "Hmmmmmm......," and
bugkiller930's "1996 Porsche 993 Gemballa Speedster Wide Body Twin Turbo S."

The eBay auction was by seller "porschec2scab."

The text of the ad can currently be read here for item #200983434128; VIN WP0CA2998TS340688.

 

Notable that seller "porschec2scab" also sells "Porsche 911 993 Body Kit Front Rear Bumper Wheel Arches Fender Flares Wing Tail," item #200786667452.










...& the last 2 photos in the ad are especially notable:





Doubtful there are the same car or were originally born as Gemballa Extremos, IMHO.

 

completely ugly. lines don't flow..... just my opinion.

 

Thanks for that, I've been searching for years for a picture that showed the roof stowed away-sorry for the thread revival!

I always worried that it would take away from too much luggage space as we love our European driving holidays but it looks like it should work out just fine. I really must find the time to go & see 9miester to discuss!

 

Always happy to help anyone's Speedster addiction
Yes, you must
Speaking of RLer NineMeister - kudos:
their latest build's featured in the current issue (December) of 911 & Porsche World

 

If 3 Gemballa Extremos were built & 1's in the U.S. ^^ please share your source(s), Marc.
Note what this auction listing states:

 

Am I the only one dumbfounded by the idea of somebody looking at a 993 and saying, "Bad lines. I'm going to improve them!"

 

Thanks for the thumbs up Jaeger!
