I've been with the RAC for as long as I've had breakdown cover - probably 15 years at least. On the few occasions any of my family have called them out they have been very good. On the last occasion, the alternator on the Omega died on the A50 whilst I was towing a trailer, and the RAC attended promptly with another battery to get me off the dual carriageway, but then left the recovery to Mansfield Recovery (who were poor) who attended on behalf of the RAC. Dispite me telling them, and no doubt the roadside RAC man would have done, that I had a trailer on the back, a young lad turned up who wasn't qualified to tow, so I had to wait for another recovery truck to arrive. Mansfield then took ages to return, and told lie after lie about initially being on their way, then about being stuck in traffic, then needing to get a different vehicle - a bit like taxi firms who say "Five minutes, mate" which turns out to be 30minutes if you're lucky. The driver that did turn up in the end was ok. When asked where the traffic problems were, he replied," Dunno mate - only just started".
But, the RAC have been good, although not all of their sub-contractors have been quite as efficient.
