The future of Mexico's first sports car company, Mastretta, is under threat due to a dispute between the brothers who founded the firm and the investment company that was financially supporting it.
In a statement issued earlier this week, Carlos and Daniel Mastretta said they had removed themselves from the company they founded in the 1980s.
The dispute stems back to last year when the brothers sought additional funding to prepare a version of its Ford-engined MXT for testing for European Community Small Series Type Approval.
In return for the new investment, Carlos and Daniel Mastretta agreed to not only have a reduced equity holding in the business, they ceded control to Latin Ideas Ventures (LIV) which installed its own chief executive.
A statement said: "On 26 May, the brothers Carlos and Daniel Mastretta announced that they could no longer work with the company whilst under the control of their principal investment partner, Latin Ideas Ventures.
"It is the contention of the Mastrettas that the new management team made poor strategic decisions, failed to achieve any of the agreed goals, and wasted valuable funds that should have been earmarked for development. It is also alleged that despite a contractual agreement being in place, investors have withheld the second instalment of funding.
"Throughout the last 12 months, the Mastrettas maintain that they have repeatedly warned their board of the potential consequences of management policies, including delays to the approvals programme, but with no action being taken on either this, or the implementation of the subscription agreement, they felt that they had no other choice than to remove themselves from the business until their concerns are addressed."
