You ever used a dolly though? What a pain in the arse!
Especially if the car doesnt run, you try getting the bastard thing off.
Once had to go rescue a mate who had a blowout on a dolly with a dead Rover214 on it. at the side of the road, we had to get a tow rope and drag the dead car off the dolly, even then I pulled the Rover, the dolly and the Freelander it was hitched to - up the road 25 yards......
With a 1.4 Corsa!
If you have the space to store it - get a trailer!
