Ive seen a intake merc mp4 tag axle today,its the first time ive seen a mp4 tag ,infact you dont see many merc tags, whys that then:? are they more expensive,are they crap,is there a waiting list,whats the crack 
Think they only came out last year,you could get a tag on the old mp3 but it had a massive wheelbase and twin wheels on the tag axle,the mp4 is single wheels and a normal wheelbase,hope this helps
