carsilike

Hi everyone, I am looking to buy this 2012 ES350 but it has some kind of residue running down the mirror. The left hand side mirror was not installed on the car. Looks like it was taped on and the tape left residue
The dealer is giving me a $2000 discount if i buy it AS IS. It has about 236,000 kms or 145K miles. No accidents or claims and I saw no signs of paintwork but I will check with a paint meter. It drove very smooth.
Is there anything major these cars need in terms of service given this mileage?

I have never bought a car with this much mileage but it seems like a decent. I'm just afraid that there might be a major issue with the mirrors?
Has anyone had this issue? Any idea whats going on?
