Car Description:
I'm the original owner of this one and throughout the years have been steadily building it up to this final metamorphosis that I've had planned for quite some time there's still a roll, cage and much more expensive suspension to be added, as well as potentially a six speed, but I'm patient and will wait for that to happen.

Used to live in Southern California and took it to track of its at streets of Willow and Willow Springs as well as Fontana and never got a chance to take it to Buttonwillow, but besides that it spent a lot of time going up and down canyons.

At this point it mostly sits in the garage and comes out on the weekend, but the plan is to eventually get it on the track here in the DFW area and get it dialed in and maybe do some amateur events.
