1975 Beta Coupe project QLD Australia

Dear All,
I thought it was about time I posted some pictures of my 1975 Beta Coupe which I have been steadily rebuilding/modyfying/competing in, which seems to be transforming from a road car into something more serious....All work performed by myself to date, and has been great fun.
The car has cost less than AU$10000 so far (including initial purchase) and has been competing mainly in hillclimbs, and has proven very successful and reliable, winning the road registered up to 2000cc class in my first year of competition and beating RS2000's, Fiat 124 spider, Alfa GTV, Honda Civic Type R and more! (Much to the annoyance of my fellow competitors who spent much more than the entire cost of my car on their engine alone!)
