I fitted a cobra seat, removed it when the lease co took it back with 110000 miles on it, still have the adapted base to fit a seat to if anyone wants it (seat was knackered!)
freelander sport seats are much better ....with the runners they are a fair bit lower and good bolsters on them and lumbar support ...they are actualy a very good seat and fit straight in but you will need them with the runners to make them fit to the best position
