Rolls Royce makes very good cars. That goes without even saying. However, if you have to ask anything about maintenance, repairs, or anything else....you can't afford it. Those are meant for people who either pay cash or don't even know their payments because they have someone to handle it for them.

Personally I don't care for the Cullinan at all. I'm not on board with a Rolls SUV, much like I don't like the Lambo Urus either. A true Rolls to me is a luxury sedan, not an SUV. But to each their own on that.

Bottom line: it's going to break, it's going to have issues, it's going to need constant attention and maintenance, and if you have any concern whatsoever about any of those things, don't even consider it or any other high-end car as they all are like that by nature.

If you wanna buy roll royce you gotta make sure you have big pockets 

They claim that it can last 300000 miles or 70 years but there is no actual evidence that roll royce lasted that long 

It Cost a fortune to fix and repair. I am talking about 3000 to 5000 dollars.

Only Roll Royce dealership mechanic can maintain modify and fix your car. If you go to any local who hmechanic who has highest end tech wont be able to any kind of repair or modification on car your car. If your forced him or given him big money to do it, you will just end up loosing your car warranty 

So if you want my opinion get lexus or Acura

But if money is not an issues your choice 

Lease it. If it turns out to be reliable, buy it out at the end of the lease.

There are no reliable luxury cars, there’s to many extras that will fail. However, if you can afford a vehicle like that why worry about reliability? You should have the money for the repairs.

Just lease it, and then get rid of before the warranty expires.  That’s the smart way to approach this.  Any ultra luxury car like a Rolls Royce (owned by BMW, btw) will have issues and break - no question about that - but if under lease you just throw the keys at the dealer and have them fix it under warranty.
