man, I really Like that style of 911, so I really hate to tell you this, but I Think this car is going to be more trouble than its worth...
It is one thing for a car to have an oil leak, fault codes stored, leaking shocks, or tires with some uneven wear, but when a car has ALL four and more, then you know this car has not been taken care of mechanically. It has been in an accident as well, and I see nightmares from the body shop at least once a week.
I looked up the European Motorsports in Vista CA that did the inspection, they look VERY reputable based on the reviews they have on Yelp, google and facebook. I am going to have to say I tend to believe their recommendations.
If you really want, I could work up some rough numbers on fixing all that, with the unknown cost of the Fault code thats stored, and also the uneven tire wear (could be mostly due to the shocks being blown out)
If this were me, it seems like a good deal, but this is one I would 100% pass on in my experaince dealing with these cars and the issues it has, plus the unknown variable in this case.
Please feel free to ask any other questions you have, I would be more than happy to answer them, and please do not forget to rate me as that is the only way I get credit for my answer on this website.
