Thinking about this gadget and almost a tenner a month to be part of the scheme, I wounder if most of us really do need it.
On my Astra its loaded with warning lights that would make me pop into the local garage for a check up, It usually costs a tenner and most times fixed on the spot if its little or nothing, or booked in for a check up.
Then there is the Vauxhall Manual that came with the car that can tell me what wrong but then I have time to do this.
Such as fleet and hire company's etc. it may be a godsend.
There's still no substitute for regular preventative servicing, a lot will just drive until the smart matchbox tells them that the RAC will meet them at the next junction for the breakdown that they're about to have!
I use one of these Vgate VS450, it saves me a small fortune in having to pay silly money to put a warning light out after I've done the repair myself.
