posessed vehicles

Aren't we getting away from the original subject of cars from hell? How can you define how long a job takes. I can do an E36/46y BMW in about 4hrs. = Alarm with 2 x immobiliser cuts, R/S , trunk release (if on vehicle) mirror fold, window/roof close, deadlocking and 556U bypass. Then give me a Mits Evo VIII onwards where you have to go to individual motors for window closeand see how much longer it takes. Also if you are working repeatedly on the same or similar vehicles you get much faster. I'm doing a tracking contract for a top end lease company and most of the M/Benz, BM and Range Rovers are taking about 25mins. each.
