Does anyone happen to know anything about Liverpool MOT in Speke (or know of a Liverpool equivalent of this forum where I could ask)? They're offering an MOT and "Winter health check" for £15 on nCrowd (formerly kgbdeals, works like Groupon)

the classic cheap mot scam, guarantee they will find something to fail you on and then hit you with a retest fee.

I did ring them (though not recently) and was told retests are free, regardless of who carries out the repairs.
