Also, getting a dolly for a car as light as the Beetle will be far cheaper than modifying it for 4-down. I priced doing it for my 03 Kia Sedona, as it's too heavy to dolly-tow. Overall, for transmission lube system, base-plates, tow brackets and tow bar plus an auxiliary brake system, it added up to almost $3500.
