What’s that irritating little buzz? Not from part of the cars infrastructure surely? Could it be from that card stuck in the lower left windscreen corner?
I just did the same on an A2 that's been stored for 5 years, it looked unrecoverable, but following a few simple techniques on RU-vid...it looks like a new car! even smells good!
I do wonder. I also bought this car (will arrive in 2 weeks) but the speedometer is the same like your's like analogue , while most yaris's have digital ones why is that?
