Are you presenting yourself? I did, and I went to Gillingham. I think the reputation isn't fair, yes they know the cars, so they know where they fail and where to look, but they also don't get bogged down with other areas on the car. Caterham South also know how Gillingham likes to see the car presented, and provided they don't miss anything in the PBC and you follow their instruction you should be fine. My tester started with the question "how do you like your tea?", he bent over backwards to try and pass my car, but we ran out of time, leaving me two minor things to fix before a retest (anything within a 6 month window). One of my minor faults was the steering rack boot rubbed on the bodywork hole at full lock. The holes needed enlarging something not mentioned in the build manual, also not spotted during PBC or flat floor setup. So should I blame Gillingham for spotting that. My other problem was the speedo liked to die at speeds above 30. Given my car was trailered to the test and not test driven I just didn't know I had that problem, but tried during the test to adjust the sensor with various level of success but not enough success to pass. So my vote would be Gillingham, and present the car yourself. Also I did my paperwork about this time last year, but my IVA test was January (just an FYI).
