As above really, i remember only a year or 2 ago the for sale section used to be filled with s13's for under £1000 in decent condition !
now its hard to find one under 3k with tax and mot and hardly any mods, any i have seen around the 1k mark have been complete buckets or need new engines ! even at that your lucky if there are more than 10 for sale, seems to be all s14's now !!
