I just adopted this orphan, an early 1990s Univega Via Carisma, for just such a purpose -- errands and city hops. It already had front and rear racks and fenders, new tires, decent shape overall. Perfect.
I'd been using my Globe Carmel comfy hybrid with a rear rack for both joy rides and errands, but it's not fun when loaded down with 40+ lbs of groceries. The simple spring suspension fork feels like a pogo stick when overloaded.
I'm hoping the rigid fork Univega with evenly distributed loads front and rear will be more stable. We'll see. The original flat bar was hard on my wrists so I swapped riser bars with my Globe hybrid to see if it's more comfortable. If not I may try some albatross or similar bars.
