Me too.. came pretty close to a purchase. He was real sketchy when I demanded having the engine inspected prior to purchase... a day later (one day before purchase) he jacks up the price by $2k.
First his wife has cancer, he needs to sell so she can retire.
Next, she's interviewing at Yale, and he wants a new BMW.
Then, his wife hates driving that car because it's too fast / abrupt for her.
Finally, his wife loves the car, thinks it's prettier than a Lexus, and demands he not sell it for less than $30k.
