2006 Nissan Quest Minivan 3.5 SE 4dr Minivan (3.5L 6cyl 5A)
Pretty Good vehicle 
 I bought my Quest brand new in january 2006 and I take good care of it, always have. It has paid me back well since I have never had any engine problems and it's going on 128,000 miles now. this van has taken me and my family everywhere. the only thing i have replaced is the engine mounts, one catalytic converter and lower control arms all after hitting the 5 year mark. it was expensive to replace these but considering the amount of driving i've done on it i didn't feel too bad and chalked it up to wear and tear. as far as the engine goes, no problemo! still running smooth like new! just take care of it and do not neglect regular maintenance services and this van will keep running well......
