Go 2010 Premium Connect, it's awesome with the hard drive - it has touch screen as well whereas the 09 doesn't. With a higher mileage check the drivers thigh bolster isn't collapsed, when you sit in the car put your hand under your right thigh and feel for foam, if you feel a metal bar then it's collapsed.
Clicky driveshafts still seems to be common on 370's as well.
Boot spring not always lifting also an issue.
Make sure it's had a P3 - spark plugs as that's a circa £600 service.
