as far as i know the black and polished ones are the euro repops, the ones ive seen i really didnt like... the flat four ones are nice tho, my only complaint was the polishing wasnt top notch... but i guess thats to be expected for the price you pay. as far as the fit goes it may fit but its going to be tight imho. 205s fill up the fenderwell on a earlier short axle bug, so with your long axles (assuming its never been changed to shorts) the tires might hit the lip of the fenders. Theres only one way to know for sure, bring the beetle down to a tire shop and have em mount up a tire to see if it fits.... not all shops will do this, but some of the rod/custom friendly shops will.
