Cheap breakdown just isn't worth it.
RAC and AA are widely considered the big two.
Had RAC cover - bent the front valance on my car dragging it to a garage attached to their depot (independent, honest) despite having onward travel and car to any destination. 45 minutes at the side of the road trying to point this out to the tool in orange.
Eventually caved in and went to his garage. 85 quid for a rear brake line that ran across the axle as a link, charged me 11 quid to use MY bottle of DOT5.1 because they didn't have any, gave me the keys back with so much air in the lines the car didn't stop on the pedal.
Just not worth it for a £2.50 part I could have made myself and fitted in 10 minutes.
When I bought NBB, I had day insurance to fetch it, with RAC cover for £3. CV joint broke on the sellers drive, around 2pm Sunday. Rang RAC, left key with seller who was happy I hadn't reneged on the deal - he told me up front it doesn't have long left. RAC would fetch it to my house. Went home in mate's car to wait for NBB.
4 hours later, no car. Hmm. Ring RAC who put me on to their contractor. Contractor tells me "Yeah mate, we can have it there for Thursday"
I went ballistic. Net result, car arrived outside my house at about midnight. Basically a 2 hour drive.
Later got an email inviting me to review the service - replied asking if they really thought it was a good idea to ask me to review it. Got a phonecall and a 50 quid cheque offered with apology. Told them to make it payable to the MS Society, they did.
Had Green Flag put to a car in the past. Useless.
Have AA cover, used it on friend's cars, and my own - they employ skilled roadside repair folk, stick to their timelines, and if their wizards can't fix it, they'll take you to Enterprise for your stay mobile car, and drop your car wherever you want it dropped. No arguments, nonsense, or damage.
Don't cheap out on breakdown, get AA. Ring a car transport company and ask them for a quote to move your car 30 miles. AA cover is cheaper than that.
Methylated spirits are cheaper than Glenfiddich, Becks, Marstons Pedigree, etc - still won't drink meths. Breakdown is the same deal.
