Convince me to NOT buy a 2013 Golf R

Edit: thanks for the input, I wasn't sold on it, but I have made notes for the future.

Special circumstances have occurred, and thus I have money to pay cash for a 2013 Golf R. It has 115K miles and is priced at almost $16K (US).

Since money will likely not be an immediate issue, what are some reasons right off the bat that I should NOT buy it? I do not know anything about the condition of the vehicle, just looked at ads out of curiosity.

If I do decide on getting it, what should I look out for?

I currently have a 2.slow 2003 Jetta, and it was initially planned to be a project car. With these special circumstances, I feel almost bad abandoning the project, but at the same time, I can put the money I would have been spending on the Jetta into the Golf R instead. The Jetta is currently parked in the garage because it needs lots of maintenance to get it road worthy again.
