So I went ahead and purchased the car. The previous owner had it for a year and a half and performed some maintenance. 3 previous owners.
The book only had 1 Lexus stamp. However, after having registered the car on 'My Lexus' portal, I found that it has Lexus service history till 98k. So that's cool.
Cam belt was done at 77k.
Unfortunately, the tilt motor and the reverse camera don't work.
Was wondering if there is a DIY fix for this.
