The meaning of this statement must have changed and I never knew it.  I see it used a lot.  Here is an example how:

"This vehicle is pretty much completely original except for the following. 1. Repaint in 1981 (Lincoln Continental Silver). 2. Factory Electronic Ignition from 260. 3. All Front Engine Components, Timing Chain, Oil Pump, Fuel Pump, Water Pump and Distributor and have been replaced. 4. Wheels with Z Spinners. 5. Rear Window Louvers & 280Z Window. 6. Front End Bra. 7. Still has original SU carbs and all emission control (air pump). 8. Interior completely original and carpets have been replaced".

Please tell me I'm not the only one that laughs out loud when I read that!  I may post more of these for entertainment purposes as I see them.

You are not alone.   Falls into the same category as my neighbor a while back that claimed her 96 Dodge Avenger was a "Classic"  ...

The opposite side of that category would be "Upgraded!" Which really means in most cases "the original well engineered part was thrown away and replaced with something much more shiny that may or may not enhance performance".
