hello I'm after a bit of leagal advice, I own a garage and recently a lot of people are getting work done then expecting to pay for it at a later date! so I put a sign up in clear view saying that cars are to remain on the premises until any outstanding balance has been paid, has done the trick up until the other day when a bloke comes to pick he's merc up, bearing in mind I quoted him 1500 before starting the job which he was ok with. anyway the job took less time than I expected so final bill was just under a grand handed the guy the bill and he went into one saying that that im a con the price is extortionate and he refuses to pay, so fair enough I say, your not taking the car until you pay! after threatening to smash my face in he leaves as my 2 very large employees emerge from inside the workshop, today I get a visit from the police telling me that if I don't give this guy he's car back at 5pm il be arrested for theft, so I explain to them that he's car is worth 800 at the most and he owes me a grand and he should be arrested, the reply to that was its not a matter for the police and I've gotta give he's car back! the police are renowned for making it up as they go along and wondering if I'm within my right to keep he's car?
