what if i told you i bought a car and its mot was done at point of sale you would think well its good for 12 months but no after 12 minutes of signing eng man light of so they agree to fix will be 2 or 3 days 6 weeks later i collect car to have all lights come back on after 12minutes. you would think that was unlucky! you would be right but if i said this has happened twice in a row you would think jesus thats really bad actually this has happened 3 times in a row and im taking legal action. this is why it happens below ac buy problematic car from auction or fail to examine a trade in due to concentrating on sale if a car has warning light they use code reader to knock them out and do not fix fault they then mot while clear knowing full well they will come back on they then sell you the car with warranty they then send you to ac to get work done on warranty and give you hire car from your warranty which they make profit on may i add they then claim to do the work but only clear codes for same thing to happen. I feel sorry for the honest local garage selling quality cars and being rigourously examined for being trustworthy while this multi national company gets away with very very lewd tactics, its so unfair. My advice Dont finance a car find a quality low mileage one yourself for half the price with a loan or credit card as finance rates are just stupid now, i think ac will collapse within 5 years.
