Oh that's rad. Great to see people around the world keeping the spirit alive. I'm pretty sure Lancia made one of the snarling, 960kg, 480 horsepower Group B World Rally Cars in the early to mid 80s loosely based on the Spyder. I have not seen one in the flesh, but seen plenty of photos and videos over the years.
One of the Targa Rally competitors here in Australia has one of the last remaining Group B Alfa Romeos which regularly competes in out tarmac rallies. I've heard it knocks out around 1000hp!
