Ah, right - actually Beechdale are also Hyundia and I have a quick story on that - shortly after they had taken on the franchise.
In December 2009 my partners Sante Fe Diesel suddenly started to run poorly, after I changed the feul filter (thinking the symptoms were due to a blocked filter) we took it to an indie who couldnt diagnose the problem after having it for a day (and charging £80 for the priveledge) but theorised it was an issue with the injector spray patterns.
I sent my partner off to Beecdale the following day who diagnosed it correctly immediately - the cam belt had slipped and caused some damage (as you'd expect), they couldnt believe she had driven it there - they sorted it out quickly within about 3 days (a lot of new parts were needed) all under the 3 year warranty which only had 5 days left to run!! No questions no paperwork just returned the car fixed.
They didnt sell the car to her and hadnt ever serviced it before, when you get good service like that you cant knock it really.
