I bought the oyster 2 last year. And it was the display model in the shop so it probably wasn't the newest model last year either. It was a limited edition model city grey.
It really depends what you need it for. I use mine mainly to walk to the local shop and through the local town and I need to get it in and out of the boot a lot also. So it suited me as it is very light.
However, I used the carrycot when DS was a newborn and he outgrew it very quickly. I think he was 4 months when we stopped using it. He was a very small but longish baby.
For some reason he hated the stroller part. I don't think it is very comfortable. The sides are very "open" iyswim. I know it says you can use the seat from newborn but I wouldn't. It doesn't recline completely flat either.
I have a Britax Römer babysafe plus SHR 11 car seat. Great car seat. I tended to just pop it on the frame for short trips instead of using the stroller. I bought height adaptors to use with the car seat and carrycot as I found the pram to be very low. These add 7cm (I think). And mean that you have more space underneath to put groceries etc.
DS is now 10 months. I put him in the stroller last month and went for a long walk and he actually slept. Maybe he is more comfortable now as he is bigger and has sitting balance 🤷♀️
I've also found that the front wheels have buckled occasionally when going up/down kerbs. So it wouldn't be a great choice for rough terrain.
In conclusion, an ok pram. I wish I'd did more research and went for something else.
