I am going to get a CPO from Tesla. Any tips on what to look out for? Also, is adjustable suspension an option or standard? Is hard top much better than soft top?
I do have a tip for you, though it's not something to look for, as much as a bit ownership advice.
Sometime soon after you get your car, and I would generally say sooner is better than later (and now realizing that this might have little applicability to you, being in Hong Kong and all), I recommend taking your car out on a road trip. For this purpose, I define a road trip as any adventure away from home in which, to get back home, you will have to charge the car somewhere "else" so that you can get home (wherever that somewhere else may be). You'll charge out on the road, or you'll get home on a flatbed (Do or not do - there is no try

).
For me, that first trip was a 100 mile drive to a charger to get lunch, and then a 100 mile drive home. A few months later, it was the BC2BC event, going from the Washington / Canada border down to the Cali/Mexico border over ~3 weeks, and back home. The point is get away from home, and get a feel for what the dynamic is like for charging away from home.
