Even though its just pre season testing and these times are not very representitive of the real order of things its encouraging to see Lewis putting in comparible times with everyone else despite the very limited running he has had in a new car/team/working environment, as skeeter mentioned it seems that the merc does have some decent pace under it, i just hope reliability can be ironed out as so far its not looking promising on that front.
However, i'd rather they have issues in testing so they can work out gremlins before they hit the first race, granted it would be even more ideal if they had no issues at all, but hey thats what testing it for afterall
