The Lenco, being a oldie but goodie, and a modified one at that, will need some M&R every now and then. It has quite a jumble of levers, springs, wheels, drive shaft, etc underneath the platter which can misalign over time I imagine ruining the kinematics and requiring some adjustments.
My other table a Nottingham Spacedeck is a minimalist one - incredible in its simplicity but very precisely built. All it needs is 1 drop of oil on the bearing once or twice a year. It's been spinning like clockwork since day 1 (5 or 6 years ago).
