Here come the questions............
Engine size is not enough - what is this vehicle MMY, miles, history?
Why do you think you need new rings? Just rings!
Did you diagnose this? How?
What are the symptoms now?
____________________________________
There was a day very long ago when the metal qualities and lubrication problems with oils that were no where near as good as today. Engines were so accessable you could do this and even stand under the hood with some vehicles. Vehicles would start to burn oil, smoke out tail pipe and you could just replace rings and get another period of time before needing them again.
Chances are that if rings are worn that the cylinder walls would be too and other engine parts too many to itemize. You would have the cylinders bored out which then means new pistons and then the bearings should go too, oh camshaft ok? how about the heads and so on.
I may stand alone but if you really need rings the engine is junk! It can be rebuilt and places still do it and all I've ever heard is they just don't last. Nobody beats the original engine with reworking it.
So tell us where you stand with this and how the whole rest of the vehicle is which matters a lot. This can't be cheap. Some parts are so are some tools but then you might need stuff that could buy a whole new car just to machine certain items.
Knowing more about this will help us to suggest what might be the best fix for this,

The burning question of "Is it worth it?" will always be there. A car you can afford is near impossible to know.
What you need to know is that the upkeep and known repairs of a used car could far outweigh the price of the car even if you do the work yourself.
The seller states the car needs rings and burns oil?? How do we know this at all at this point? Does this seller really know that and is now selling because he/she found out how much it would cost to repair?
If you have some time and like this car do some info gathering. Start with a hard look around the car for damage or poorly fixed damage. Is the interior ok? Do all accessories work?
If you get there and still interested take it for a test drive. Bumps, corners stops and starts. Still OK? Take it to a shop not involved and pay for a check out of the things known and look for the unknown. Get estimates of what it needs or may need soon.
If you live where inspection of vehicle for safety and emissions are required know that you will have to pass or not drive that car and the expense to get it to that could be a killer.
I expect your car to be safe. We share the roads. Emissions need to be ok too or the car will have problems with other things if they aren't in control. It's all expensive now so the more you check it out the better.
Still interested about the history if known. Is this seller the orig owner? How long have they owned it? That would be nice info,

There could be other reasons for the oil usage. A plugged PCV valve could cause that. Worn valve guides and seals caqn also cause it. You need to do some diagnostics before you get head set on the rings. Good luck with it.
Being way2old is why I need help from younger minds
