VRS squealing/metal scraping noise at high revs.

[ESP800]

Test drove a VRS for the first time today and every time I put my foot down and went to the top end of the revs (tested in 2nd 3rd and 4th) it would give off an intermittent high pitched squealing noise.  I'm not the most clued up on cars (trying to get better!) so wondered if anyone knows what the issue was? I'm going back next week when the garage has given it a once over so will see if they noticed the issue and sorted it out.

 

Thanks!

I'd probably swerve that car and look elsewhere if I were you.
