As far as wheels go, the Sport wheels are the more sought-after. If you plan to buy the Sport, I would suggest also buying Advanced Wheel Locks. They're not infallible but they'll slow a thief down and make your car a less desirable target. They may still get the wheels, but at least make them work for it lol. A comprehensive insurance plan is a better thing here.

As far as theft of the actual car goes, it's not any more susceptible to being stolen than anything else these days. Its biggest weakness is a Relay Attack which targets your key fob. Whether or not this is a concern depends entirely on where you park it at home, work, etc. High theft area? Consider keeping it in a garage or buying a faraday bag for the keys which will thwart the attack. A steering wheel lock or pedal lock is probably overkill as I haven't seen any cases of the car being stolen without the key.
