Please note this is a CAT S Vehicle that was fully repaired when I purchased it. It is still in great condition. It's never given me any issues except that I had the exhaust pipe changed recently due to a hole from speed bump. There is a whirring sound when you turn it on, I've never known what that was but it's never bothered the car or performance in the 6 years I've owned it. The sound goes away after a minute or two. Apple car play is great, and fully functional. I bought the car from a friend of mine it's a great car!
