Re: 2nd Hand car from garage
As far as i know, the goods you buy have to be fit for the purpose for which they are bought. I would be of the opinion that a seriuos wiper fault would indicate that this was not so in your case.
There is also a seperate issue in relation to the way the car was advertised, 2 previous owners versus 7. Should i find myself in a similar situation, I would strongly argue that the garage take back the vehicle and arrange a swift refund. Should they prove unwilling, it may be worth checking to see if they are registered with SIMI and taking up a complaint there.
On a contractual basis, there is the possiblity that a contract could be declared void ab initio on the base that there was a fundamental mistake made - i.e. you thought you were buying a car with 2 owners when in fact it had seven. I would think it fully possible to argue that 5 extra owners made the car you actually bought materially different to the one for which you contracted.
I would not take this as 100% concrete legal advice (it has been a few years since my direct legal experience has been practiced) but i would be pushing strongly - sometimes a well drafted letter outlining your expectations and warning of your next course of action will do the trick.
Good luck
