How do we feel about ‘3 owners’?
As with the mileage, it could be lower, it's not unreasonable for a car that will be 5 years old in 2023?
This car has been well specified and was not one of the cheap lease deal cars, it would have cost too miuch, On that basis, it has probably had owners who have sought out a car like this and probably looked after it, so three owners is plausible.
Conversely you could find a 3 year old leased car come up for sale that has just been a tool and not looked after by the single owner. I'm not sure that is ideal, despite the low owner count?
You probably need to look it over in the metal to see how it has been cared for, there don't appear to be any obvious issues from the photos.
As many of us said at the start, you will probably have to compromise on something finding a suitable GTi in the right spec, at the right price at the right time.
