Exhaust filters do not apply to T 1 n sprinters from 2007 and below . Some t 1 n ' s have reached 1 million miles . EGR maintenance is important , as is changing transmission fluid . Transmissions do wear out , but it ' s simple to rebuild them with new clutch packs and solenoids . Electronics can go bad just like any vehicle , and wires need to stay protected . Only weaknesses to watch out for is injector seal leakage and the turbo muffler resonator needs to be replaced by the updated $ 30 part . The T 1 n is a very dependable vehicle from my research and personal experience . The new sprinters are built to fail , do not buy . <| sep |> Why does it matter that some countries briefly hit higher levels of GDP growth ? Except for Ireland , none of those countries have had sustained growth that high since the recession , and most of them follow the developed nation trend and have growth very similar to that of the US or worse . For that matter , New Zealand never actually hit 3 % during Obama ' s presidency . The last time it hit 3 was in 2007 . And your original point about GDP growth is probably incorrect , considering we don ' t have accurate GDP estimates for a lot of presidencies . And , if you look at the quarterly GDP growth , Obama has actually gone above 3 % all the time . g d pgrowthratetablebyquarter Stimulus spending probably avoided an even worse recession . And the US debttogdp ratio is pretty standard . I would say Herbert Hoover and Thomas Jefferson were way worse .
