That is why you advertise and sell it yourself and pick up the difference
Well, for what it's worth, the car (2002 Lotus Esprit 25th anniversary #80) was unofficially for sale for 3 years. Not really advertised, but offers were extended to those who asked about it. Asking price was $40K but I was willing to work on that. Price sold to Carmax was $28K and it's been found for sale with Private Collection Motors for $59.888 which is at the very extreme high retail end. Knowing what work the car needs (minimum 10K) to bring it to almost perfect condition, its just not worth what they're asking, in particular with the "higher" mileage of 38K. Overall I had the car since 2008 and aside from a few extra repairs, all maintenance was done according to factory schedule and the car was rock solid in reliability. Not at all the troublesome vehicle people make Lotus to be. In 8 years it never had a breakdown or left me stranded. I do miss the car, but it was getting to a point that my body and the driving position required just weren't in agreement anymore so I felt it was time to pass the baton to someone else who could not only appreciate it aesthetically, but also for the unique characteristics of such a rare piece of machinery.
But keeping in context with the original message, I would definitely suggest watching google for the VIN. You might find it locally and if the price is right, you'll know what the history of your car is, and be better suited to make a buy-back bid that might be more in line with what you feel is a fair offer. Unfortunately you might also find that the best you'll be able to get is about what the lease buyout price was since you now have a dealership that needs to make profit thrown into the mix.
