2 months in to ownership, from what I can say:
You will definitely recognise the chirping noise. Mine gets it when I run on 98 but ran it once on 95 where it didn't happen. Not noticeable 99% of the time unless you're outside the car standing near the bonnet whilst it's running for whatever reason.
Auto will miss the gearbox issues
I've got the rusty door pillars starting to show now however I think if you catch it early you'll be able to prevent it.
I went with Toyota Approved from Listers in Nuneaton, had no issues with that.
Unfortunately mine's been involved in a crash already though, small bump so got off very very lightly, other two drivers are in intensive care a week later. Non fault as someone went to overtake me on a blind resulting in head on crash. Waiting on insurance now which is going to be a sad one to see added when I come to renew seeing as though I'm 18, 19 at the time of renewal
100% a fantastic car to drive, I don't feel like it needs more power, may think differently down the line but it has a nice amount as it is.
