OCC doesn't slap a bunch of plastic filler on a quarter panel and call it good. Okoboji Classic Cars is in the business of real restoration. That means looking at each area of the car and determining what will best repair the damage. We not only look at the cosmetic, we also look at structural strength and longevity for your car. We know that straight site lines must be laser straight and each curve must be perfectly smooth. From dents to rust, our professionals turn back the clock for your pride and joy and take it once again to its' showroom glory days. Restoration Shop Hours: Monday - Friday, 8:00 am to 5:00 pm.
