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.
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.
