Opel Manta Clubs - V8 Register
The V8 Register has been going for a number of years now and caters
for modified Opel Mantas, particularly the V8 variety. The
V8 club is most welcoming of any Manta with improved handling and
performance and at their meets that's all you'll ever see - V8,
V8 and more V8s. Lovely.
