Hi guys sorry I'm writing this in English but I'm wanting to know whats the main differences between the later 1300 1400 and 1600 turbo tractors apart from the hp would a 1300 turbo be as good to buy as the bigger two? Ive seen a 1300 turbo for sale but was wondering should I hold out till I find a1400 or 1600? I'm in the uk and it's not so easy finding a mb trac now a days
