Get...Bent.
Block heater is a must have, the rest of that stuff is BS. They may try to tell you "nitrogen is already in the tires, we've already done the security etching, blah blah blah". Tell them to either take it off or walk away and go elsewhere. Locking lug nuts? Ya, cuz peeps our out there jacking rims off a Kia and it's the locking nut that's going to stop it. In the 15 years I've been doing insurance I've only had one client's factory rims stolen and they were off a GMC Denali. Add to that only a handful of aftermarket rims have gone missing. This isn't Detroit, it just doesn't happen all that often.
