What kind of value do you put on your truck? A notch like that, if its clean, are going for 6-7k up here in the rust belt.
Yeah you can daily drive them no problem, but lowered foxs ride like a box of rocks. Mines lowered 2" and I drive it every nice day I can. Its been a great, trouble-free car for 5 yrs now. If you've always wanted a fox, I'd say sure, do it. But if you like your trucks versatility, reliability, quietness, well only you can decide. Good luck
