Hi All, I am new to the forum and Subaru world so I apologise if I sound stupid.
I am looking at this car https://www.autotrader.co.uk/car-details/202109097169125 Reg L444 DRL
I noticed that the rear arch has some rust, I read online that it's common for the inner arch to rust which is an expensive fix but I'm unsure if that only really applies to the classic models?
The mot history seems quite clean however it has undersealing as an advisory for a few years. I am weary that it might just be a cover up job, is there any way of knowing?
