1) Unless the car has aftermarket rear camber arms, you might PAY for an alignment, but you won't get one. In fact, unless it has the aftermarket front bolts, they can't even do a front end alignment.
2) If the car is driven hard in curves, the inside of the rear tires will be down to steel cords long before the outside will be, this is normal. Do not expect uniform tire wear from these cars.

You can have the alignment checked, but I'd bet you will find it is within specs.
