Hi, Im in the market for my first ctd i saw one today in an add its a 1999 4x4 quad cab with auto . I have been shying away from autos because there more expenssive to deal with and i want some thing that will last awile . Any way the add said many extras so i called it turns out it has a DTT trany in it and alot of upgrades fuel system upgrade,injectors,turbo,gauges,exaust and it has an adjustible computer . It has 57,000 miles on it and he said the upgradeds where done at a reputal shop . Im just woundering if i should worry about mods will they shorten its life alot? Would i be beter off buying one stock? It sounds like a good set up to me i like the fact that it has an upgraded trany and fuel system in it but im woundering weather i would be geting in over my head with all the mods fixing it i would have find compatable parts . Meaning i woluld,nt be able to just got to the nearest dealer for parts . Thanks for reading i whanted to see what poeple here think about it
