Maybe i'm too new on this forum to give an opinion, but i thought single wiper conversions are a bit played out in 2009.
I'm not against them for any real reason, just never seen them look good on a golf, esp if left to park vertical!
I'm driving 2 single wiper cars atm. The 190e with its ROBOCOP arm, and a fiat uno. suits fiats stying quite well, the merc actually clears screen well with its cam action.
