For whats its worth, here are my thoughts.
Go have a look and a drive first. You can check out pics over and over again, however go and have a look. Whilst I understand the motivation of a well priced car (its been for sale for a long time) if its a turd of a car... then its a waste of your money. Not all cobras are created equal.
I remember looking at the pics of one for sale many years ago for weeks and weeks.... when I went and checked it out.... was very disapointing.... then the drive was even worse. I walked away and never gave it a second thought....... but I then opened my budget up. Dont let the price be the motivator, a compromise can be a costly exercise.
I understand the cobra 'thing'... I really do...... you either have it and cant get rid of it.... or you dont really have it at all.
$25K is good coin for a car, whilst not cobras, here is just a few things that this much coin can get you. I am not comparing these to cobras, just throwing things in the mix.
