I own a Contemporary and have been overall very pleased with the solid frame and overall originality
. With that said I did not like the pedal assembly that came on the car and have completely reworked the brake system. Body, Rear end, etc. Besides ERA, Kirkham and very few others will have all the top shelf components like KK mentioned. Mine came with the Six-pin Trigo wheels, 427 SO, E-trype rear, Chrome moly half shafts, etc.
Best of luck and feel free to email or call me as I would be much better at articulating my thoughts - both good & bad about my car.
