totaly agree with you Nick, I used to banger, and some of the car I raced werent even fit for crusher, A lot of people see the cars on the track and think, well they run and look good in there shinny paint (yes I used to give my cars a blow over to make them look good) but never came to the pit to talk to the drivers, If they had they would have noticed the amount of cars running "Strange engines" I race quite a few cars using the same 2 litre ford (pinto for the train spoters) engine.
from jags to granadas (never a p6) but I once did race a p4 100, that was so rotten that when I got it back to get ready to race it left more on the flat bed than came off, (this car was basicaly a very rotten shell and it took 3 weeks of welding and bodging to get strong enough to pass to race)
Banger racres also (or I did) seem to keep loads of bits of , screens lights trim etc these coming on the market to help those that wanted to restore cars, many of the granada racers I knew also had very nice granada road cars.
