If you have signed the contract and paid a deposit, you have entered a contract with the garage to buy the car at said price the garage has also entered a contract to sell you the car as original deal. Tell then you want to continue with the contract as original, if they are not going to honour them half of the deal you will report them to trading standards and its a nice little story to appear on BBC watchdog. They have more to loose than you as its a big dealetrs its their reputation at stake.
the contract t&c's explain that if the dealer does not deliver the car within 28 days of the estimated date, i then can write a letter to them to say i need the car within 7 days. if they still don't deliver the car then i am allowed the right to cancel the contract with no liability and they must return my deposit.
the contract t&c's are their to protect the dealer in my opinion, and not the the buyer.
i see the above clause as their 'get out' if they decide to change their mind
If i had time to pursue this i possibly would, however how can they possibly sell me a car with a broken gearbox? they simply can't do it can they.
if i ask to take it for a test drive i would imagine they would say i can't as it's broken. i don't have the power to prove them wrong!
i wouldn't want to spend a lot of energy arguing with them to be honest.
Also, they know my name and address details and I'm not in the business of ****ing someone off to the extent that i am worried they could come round and attack my property - weird i know but it's the way my head works!
