Have you got breakdown cover?
And alternative might be to hire a car trailer/ buy a dolly (ebay) & ask a mate with a towbar?
Just a couple of options.
I think recovery companies charge an absolute fortune hence the rise in popularity of breakdown cover.
Probably between 160-250.
I paid my mate 65 quid. Nottingham to chesterfield. 28 miles one way as he was in nottm anyway.
You can buy a solid draw bar from machine mart for about 10 quid and I'm pretty shure they're legal on motorways. With the saving you could pay a tramp off the street to steer the other car.
