Convertible TR in Aspen

I spent 1994 in Aspen snowboarding and working at a detail shop. The shop was Downtown Detail and some of the cars that went through there were fantastic. Working there got me more interested in sports cars and led to me owning my own shop.
One car in particular stood out for me and I was wondering if anyone happened to know anything about it. It was a customized testarosa. The color was white and it had been turned into a convertible. It was probably a couple of years old at the time. The owner of the car owned a home just downvalley of Aspen, but did not live there full time.
I know my description is very vague but maybe someone knew this car.

 

There aren't very many convertible Testarossa, so I'm sure someone will know something about it.

 

White Straman (?):

 

How many white Testarossa convertibles can there be?

 

That might be her. Sure doesnt look like Aspen, but the car was not modified there anyways. If I remember correctly it did have a red interior.
One time when this car came in we cracked the front airdam by hitting a parking block. We spent a good part of the day repairing and painting it and everyone was concerned how the customer would react. When the housekeeper (not the owner) picked up the car he told us that it was always getting broken and didnt care at all that we had fixed it.

Thanks for the picture

 

I am guessing that it most likely is a Straman Spider and from what I gather is that they had converted two in white. The one Imola2001 posted a link to, I believe is 73433. The other white one is 79343, but I don't know the interior color.
