Well, an honest testimonial for getting a PPI! Nothing riskier than a super cheap Boxster.
I learned my lesson the hard way when I bought the black Boxster roller that is now my race car. Seller swore that the only thing wrong was a failed engine. Only later did I find all of the other things that he neglected to mention.
Wishing you the best and let us know if there is anything that we can do to help as you move forward on this car - once its basically sorted, it should be an excellent track/DE car!
