I think I can do better in-terms of price. 325/328 is less than 30k actually. Repairs all in probably 10k. Anyway I don't mind the age of the car as long as it's in great condition (no rust, preferably serious-accident-free)
This is your main problem. Your level of 'great condition' is actually showroom condition to others. I still remember the pics you post abt yr previous BMW which u insist is not completed yet.
This is my finding in your 'case':
1.The suspect does not seem to be having problem in the budget dept and he understand his capacity very well.
2.The suspect has no problem and understand the risk and cost involving purchase of 2nd hand 'premium' car.
3.The suspect knows what is he looking for and wont be influence by others.
4.The suspect shows indication that he is having an emotional side effect after the previous purchase.
5.The suspect is believed to have confirmed 80% on which one he wants to buy.
Conclusion
The suspect showed indication of which car he wanted to buy and had most probably decided in his heart & mind. The reason he havent decided to do so is because he is not under time constraint and his level or requirement & expectation is well above other normal buyer.
