Sl 350, rental vehicle – buy?

First of all a warm hello to the community of Motor-Talk! I have registered with you, because I have the following concerns and I want to get some opinions about this. I am about to buy an SL 350. The car was first approved in May 2009 and has a mileage of about 19000 km behind it. It looks outwardly spotless, drives flawlessly and is driven by a Mercedes dealer. In addition, it has a two-year warranty (young stars). The price is also quite attractive. The only “manko”: It was a rental car of the company Europcar. Now my question, can I access here without hesitation? Will such cars be driven in? Has this car been tested on the heart of my heart? Can I expect a performance that I want with such a young car? Greetings
