Never, ever buy a vehicle without test driving it first.
I once purchased a Mitsubishi Endeavor without test driving it. Everything seemed great, the engine, body and interior were in perfect condition. Not only that, the seller told me that he was a mechanic and that the vehicle had zero problems.
I was so intrigued by the great price, I didn’t blink. I made the deal and drove it away. Two days later I realized that the vehicle had a bad transmission which was a $2000 fix. I ended up selling the car AS IS for a loss.
So let me say again, ALWAYS test drive a vehicle that you are interested in purchasing.
