The R32, nice atmosphere and feeling. Not the best for operators though, when it rains outside, it rains in the cab too.
Luckily the R32's are getting phased out, I'll miss them, but I feel better on an R46 and above (excluding the R179, those lemons can rot in the ocean).
I've had it worse on an R42. Had one on the J that was a constant pour. Good thing I could step out the cab in-between stops (C/R)
