Quoted from tmuir:

I own a 1961 BSA C15 motorcycle, its heavy, its slow and has terrible brakes.
There are plenty of modern motorcycles out now that are made to look like a vintage or classic bikes.
They are lighter, run on unleaded petrol, have better brakes, go longer between oil changes, parts are easier to get and probably go faster too.
But would I want to own one?
No because I like the simplicity of my old bike and like the fact it has age to it and I'm keeping it running so I can pass it on to someone else.
This is a bit like how I see VP.
Yes it's newer, can do more and be upgraded easier, but I wouldn't get the same joy from it I get from keeping my 40 plus year old pinball machines running.
To be honest my 1976 Chicago coin Hollywood is a 'bitch', it always breaks and I'm always needing to tinker with it, but to me that is half the fun.
Laying the 6 foot long circuit diagram across the table and tracing my way through it to work out which contact has gone out of alignment keeps my brain functioning.
I just don't think I would get the same fun out of a VP that doesn't need any TLC to keep running.
But that is my personal opinion, others may hate having to keep maintaining there machines and I guess that is where VP comes in.
