If it were my 30k (no chance) i'd buy something practical for 5k ish, something silly (a z4m) for 20kish and still have 5 k change.
having said that and if you must have a new car, I test drove the 200 at the weekend. It's a huge advance on the 182 and I absolutely loved it. If you want something to use every day and still do half a dozen trackdays a year in, I would get one. Renault are doing some very good finance offers too, which would free your 30k up for other things and not have it tied up in a depreciating asset. Hopefully they are still doing these in June, at which point I will be ordering a 200, in black, black speedlines, cup chassis, recaros, spoiler and cornering lights.
Not driven it, but the Meg is a different sort of car I would've thought, heavier and more refined I would expect, but not so good as a track car and also would have higher priced consumables - bigger wheels and go through brakes quicker. If you need something like that though, I'm sure it'd be pretty good. Other point to make is that its the first edition of the current model and Renault usually make significant upgrades and improvements when they releases the mark 2 of any model.
