Car is fast. has won numerous Autocross first place finishes and first place season finishes.  I have completed the work during my nearly 10 years of ownership.  It has been my passion and hobby restoring this vehicle.  Engine and drive-line is a 10 out of 10. paint is good except Rear fenwr has started bubbling from 10 year old paint job.  Paint still shows well.  Interior is very nice for a car of its type. no radio. no AC. no heat.  Car has way more than I am listing as I have forgotten much of what I have done over time.  If you have questions let me know.  I am selling as I have new hobbies and am ready to move on.  Car is sold as is with no warranties of any kind.  Many spares included
