Hi. I hesitate to say, given that so many people are waiting for their 500c, that I picked up my beautiful car today - 1.2 lounge, red, black roof! All perfect with one slight exception..... getting some juddering (occasionally) at low revs in 2nd and sometimes 3rd. Not sure if this is just a 'new' car thing, the fact the poor thing's been stuck out in the rain for two weeks, or something I should be worried about.... any thoughts experts?
