I know how difficult it is! It took me nearly two years to find mine...because I was picky too. It had to be a 1.6 and it had to be blue! I wasn;t prepared to part with my money for anything less!!
Because the 1.2s are quite nippy,they were more popular. None of the dealers I went to had a 1.6 at all and you dont see many driving around either.
I found mine on autotrader earlier this year and bought it privately. But, because it took me so long to find, I had managed to save up more money and get a newer one than I had originally intended!
Good luck!
