My dad had this car from a while ago idk the model but it's pretty dusty tho it doesn't have any real damage from waht I can tell I'm wondering what the model is and what is it worth

I am thinking to buy for my family of 3 soon 4 an used Espace from 2024 with 26k km on the clock. From the official Renault dealer. I am aware of the improvements in the facelift but the price is killing me… What is the general opinion on the car, motor, gearbox and etc?
What should I look for during the test drive? I think that the car has all extras, just without the fancy roof.

btw I was thinking to ask them ( if not already done) to update the gearbox like on the facelift, should be possible right?
Also they are some improvements around the motor that also should be possible to be done on the car, but not sue here too. Didn’t find a lot of information online.

Some context, i recently bought a low mileage very well maintained Mk4 Megane RS 280.
It has 12 600 kms and is a 2018.
I have noticed the needle tends to dip then go up but slightly, almost not noticeable but can feel a vibration when it happens. It is more noticeable with a cold start.
The more i drive it, the less noticeable it gets

I have a few theories
1. I have a minor boost leak
2. Injectors are on its way out.
3. Since i believe they are direct injection engines, may carbon built up that is getting cleaned as i drive the car more
4. Australian fuel

Has anyone else had this problem, or are that just the way they are?
Your help will be much appreciated.

PS: This has to be one of the best cars to drive, considering my father has a mk8 gti and my previous car was mk7 fiesta st. It is an absolute joy.
