Matt, used them for many years for servicing on my 4x4 cossie. Couldn't fault them really, car ran without any problems for 7 years (and still is), however, as the years went by, I felt as though they were less and less interested in my custom, and I kinda felt like I was wasting their time

Straw that broke the camel's back was last time I went after I rebuild my cyl. head. Car had a high idle, booked the car in for rolling road setup, chap there plugged some diagnostics thing in, said MAP or TPS. Changed the MAP sensor = no change. Looked at the TPS from across the workshop, said "oh, that's a 2wd TPS (on a 4x4)" and used a known working 2wd TPS, same problem.

Turned out (as I found out at home and thanks to PF), that the TPS was in fact a 4x4 one (wrong color though), and it was incorrectly adjusted. So I managed to fix the car myself.

I paid £95 to be told car had to be booked in for a full electrical check at a cost of min £200....

I wasn't impressed by my last visit. Rod convinced me that Sheady would in fact service my car (didn't think he would).

That's about it.
Hope it helps
