Took awhile but Mersu is running again and better than new.  Jouni did a huge job on weekend in first fixing and then washing, vacuuming and polishing allover the car.  Looks really good now.  We still have the BMW as a backup because the part which was broken in Mersu is fixed with a workaround (welded axle shaft or something).  Spare part is coming by mail.  Reliable car is needed on Easter as we have booked a night in spa called Eden at Nokia (town close to Tampere) http://www.rantasipi.fi/hotelli.cfm?id=Rseden
