thats a reasonable time for Meremere Dragstip, its not the best. Took a Nissan Pulsar VZR 170ps down the track and it only did 16.5sec 1/4.
unfortunately I dont really get any spare time these days with 3 young children and even thought the March is economical with petrol at $1.91/l I am only driving when I have to.
What are the specs on your March Xalelexx?
