What you need is a tilt trailer. Depending on the weight of your car you may be able to get under 4k lbs. I towed my car on one, once. It was just big enough to get the car on with a rating high enough to haul it. If you can find some of the old photos of old Cobras being hauled to events, some of the guys were essentially using a "very" stripped down version of one of these.
