A Spanish company is reportedly in financial trouble because it was not paid by the struggling F1 team Hispania.
The AS newspaper claims HRT breached a verbal agreement after ordering three new transporters from Cec-SA.
The report said the trucks are now sitting idle and waiting to be paid for and collected.
"For a family business like ours this is a heavy burden," said boss Victor Mendez, with the report saying Cec-SA spent EUR 300,000 building the trucks.
We had a first meeting with (new owner) Jose Ramon Carabante, who assured us he would fix everything
Mendez explained that it was departed HRT team founder Adrian Campos who commissioned the trucks.
"We had a first meeting with (new owner) Jose Ramon Carabante, who assured us he would fix everything.
"But from then we had meeting after meeting, the last a few weeks ago at the Montmelo test, and no solution is reached.
"We have nothing signed, but plenty of documentation that proves everything was commissioned by them (HRT)," he concluded.
