It doesen't give out black smoke at all, i was driving behind it on the motorway, whilst my brother was in the golf ahead, and he pressed it quite alot, and it didnt smoke at all... its a complete minter to be quite fair... and the bloke who i bought the car off, has had it from new, when it were 3 weeks old, and he said to me, it's never had a poke, its been like this from the day i got it...
Then he went on to compairing with his skoda fabia diesel, saying that shift's better than this lol...
