How many miles on the car ?
How many miles on VO ?
What are they asking for the car ?

I am not a fan of Greasecar kits because the design I am familiar with did not get the VO hot enough to run safely for the long term health of the engine. Not being a fan, I have not really looked at their systems in the last 5 years, so it could be just fine.

I run VO in all my cars and motor home. I would be very cautious about buying someone else's VO vehicle.

There are 2 big variables:
The fuel is home made. It could be good clean fuel with no water... or not. And... the quality of the fuel can vary from batch to batch.
Water in the fuel will ruin the IP.

The operator is the weakest link in the system. If they have switched over before the fuel is up to temp, or have not remembered to purge the fuel system before shut down, the rings will become impacted in their grooves. This happens over a long period of time.
Running cold VO will result in impacted rings eventually. (Water injection can reverse this damage in some cases.)

If the car has been run 100k on VO, then the operator has been using good fuel and good practices.
