Never ever believe 100% what the seller tells you... I know it because I sold used cars
unless you have someone there in that state that knows about cars, I say you must travel to see the car and check the condition of the car
and how much extra you should pay for a local vehicle is what you consider is right. Take a calculator or do some math to see if that car is convenient: how much money for gas, couple of sodas, meals, and TIME you spent going to that place
Only once I traveled for a car, 2 hours to be precise. And I did it because I saved 1000usd including the bus tickets, gas, tolls, etc
