To all who responded to my request for assistance on the Mercedes, My greatest appreciation! Today I expect to get back on it, (the last couple of days were either busy working in the garden, finishing up last winter's stuff, and preparing and planting early spring stuff... then it rained.. and brought water back to both my little creeks!!)
I'll keep you posted, and I'll rejoice again when I smell the scent of veggies in the exhaust of this car!
