Those ******* from Trade Car Centre, Walley Street, Biddulph, Stoke-on-Trent ST8 6EA seem to have form with regard to auto gearbox problems, a few years back I was looking for a more economical replacement for the 2.9i Granada Scorpio I was running at the time ('88 E Reg) I was looking at a 2.5TD Granada Scorpio from that very same place ('95 m Reg) which surprise surprise only had 3 working gears! - the Ford A4LD autobox is a 4 speeder - those scrotes were adamant that there was nothing wrong with the M reg car they were selling,even when I pointed out that my petrol 2.9 had the same 'box that clearly had 4 working forward gears.
As already mentioned by many, avoid Trade Car Centre, Walley Street, Biddulph, Stoke-on-Trent ST8 6EA at all costs.
To concur with Sone, Hodgson Cars have a very good rep.
Just out of curiosity, no good dealers in Warrington? - I often see nice looking deals at a dealers on Hawleys Lane (Near the old James Irlam / Stobart Yard) - just a thought.
