Thanks, ***** ***** has no effect upon your statutory rights though. You are protected under consumer law here - statutory consumer law (under the Consumer Rights Act 2015).
You should sue them for the cost of the repairs - you should obtain a report from a garage to confirm the car is faulty and is likely to have been faulty from the outset. Once you have the report, you can threaten to sue the garage for the cost of the repairs (and if you win, you can get the car repaired at another garage). You can also report them to Trading Standards on 0808(###) ###-####
Once you have a supportive report, send a copy to the garage with a letter before action (see template attached). Give them 30 days to pay, assuming they refuse to pay, you would then need to issue a claim using the simple procedure in Scotland here:
For claims over £300 (up to £5,000) the court fee is £104. If you are in receipt of certain benefits you are exempt from paying the above fee. The fee exemption can be applied for at the above website.
Once you start the claim the Sheriff will register the claim and a timetable will be given to you to detail how the claim will proceed. For this size of claim you can easily do it yourself without a lawyer (or come back to this site for further guidance).
