The answer is 'maybe' you can get your money back.

It all depends, really. If you have paid a deposit on the basis that you will buy once the issue is fixed, then you have (whether in writing or not) made a contract. As such, it is enforcable in law.

So if the garage really wanted to, then they could force you to buy the car, at the agreed price, once the car has been fixed.

All depends on what the garage's policy is, and on what basis you paid a deposit, really.

Hello all Well i went to available car and found a 2010 ford galaxy 2.0 tdci zetec , 50k miles 3 owners £10k fair price for a galaxy , all was good till test drive, its an automatic and idling in park was good, we gave it some and sounded as normal etc, only from PARK to DRIVE then it started to judder, low revs and then cuts out. Tried a few times and same thing, once you start moving though it works fine, got plenty of power, smooth gear changing etc , until you slow at a junction, it starts to judder slightly but doesnt cut out, just seems to do it when you first pop it in Drive .. I have reserved the car awaiting this fix and an mot etc , does anyone have any idea cos im going back next friday unless it sounds serious to anyone and i can get my reserve money back. Thanks

That would be 3 previous own in 5-6 years. I guess the last own didn't have the car very long?

This sounds like a auto gearbox issue which often fox dealers, plenty of other cars so walk away!

Infact push back to the dealers and say "why are you trying to sell me this broken one, dont you have a car that works properly?"
