So just to be clear you're going from a 112bhp 2.0 to a 105bhp 1.2.You're right - it's not all about engine size, the output's pretty lame, too.
I drove a Leon with that engine, thought it was pretty good, but prob even better in the polo
Why didn't you just get one a couple of years old? More car for the money, plus probably a better engine, all for less.
