I agree with Sean,
Just read the above, I suggest you do too.
Unless someone has done a restoration on it, it looks bad.
Especially as the MOT tester has repeatedly stated that the “underside has been under sealed “
My buddy owns an MOT testing garage and if they can’t see the issue, ie the rust they don’t necessarily fail it. Hence the tester is stressing the point of the underseal.They don’t poke sharp tools into the underside of people’s cars. The tester seems like he is between a rock and a hard place. His hands are somewhat tied.
That said, the garage who are selling it may have restored it, replaced the trailing arms, bushes etc. We do it and it’s a lot of work, but it is very unusual for a dealer to do so.
I’m so tempted to go and look at it.
A bit like the 33k Arctic ZMR that sold for £11k ish on eBay. That car was originally left hand drive, had had the engine bay painted body colour and had been in a police compound!!! Alarm bells or what? I feel worried for the new owner.
