I've just bought a stilo 2.4 prestigio loved my abarth and couldn't wait to get this one but alas, on driving home it seemed a bit down on power but I thought as it needs a big service, can belt etc it was that, but now I'm home on starting it from cold a huge white cloud appears its gone after a drive and its just had a terraclean don't know if that's anything to do with it?? But it defo wasn't normal and I'm seriously worried as it also seemed a bit juddery too it's a 55 72k car any help would be

Get onto the seller and voice your worries immediately. Tell them of your concerns and say it's coming back if you cannot sort it cheaply.

Lots of white smoke (steam?) could be, in worst case, a blown head gasket, but the I'm sure the 2.4 experts will advise.
