when it feels like giving u problems, it will. half cut depending on mods that come with it. std mk5 half cut now around 3.5k-4.5k if u can find one. engine lantai now also cost 1.8k edi
this forum is very pushy, keeps telling me to post after a while.
So yeah, get a rebuild... what theseira said. For the price of an unknown quality half-cut, do a quality rebuild. Half-cut prices now down to 5K i think, depending on who you buy from.
