My condolences on the loss of your brother. I agree with SMGCO on keeping the purchase objective and I hope the owner will have some empathy for your situation. Its still just a car and I'm sure your brother wouldnt want you to put yourself in a financial bind buying the car at a premium. Maybe my lighter story of an emotional vehicle transaction will put a grin on your face and put things in perspective.
I knew a real nice lady through a working relationship. She was a hard worker, mother and faithfull wife. I did'nt know he husband except by his reputation as a bit of an A hole. It came time for her oldest to head for college and through a conversation I had with her she explained that her husband had not put as much money away for college as she had expected. Her husbands solution was to sell the 67 camaro convertible that her father had bought new and she had driven to college herself and was hoping to pass down to her kids someday. I expressed my desire to buy it at a fair price for both of us and it turned out to be a very emotional transaction when she turned the keys over to me. Although it was just a standard 6 cyl with plenty of miles, each and every mile was a memory for her. After a year or two had passed I got a call from her saying that she and her husband were in the midst of a bitter divorce and her attorney would be contacting me regarding the car. It turns out that the reason "hubby" did'nt have the money in the college fund like he was supposed to was because he dark holed money to support a little "honey" on the side. The attorney calls and tells me part of the settlement was written right into the divorce that the car would be bought back at whatever it took to buy it!!! This nice lady gets her family car back in better than sold condition. "hubby" gets his mid life crisis scratched. And yes....I end up replacing the 6cyl ragtop with lets just say a significantly upgraded version
I realize your situation is different but this story just points out, as I think your brother would have agreed, that cars, money, or even a little "honey" are'nt the most important things in lifes list of accomplishments. You cant take that stuff with you
