any useful diagnostic tools for Nissan?
 

Last week,i bought a Used car Nissan . it has run 50,000 kilometers. I want to get an overall car diagnosis. I want to know how much should i afford to overhaul it in garage and what diagnostic tools should i need if i want to overhaul it by myself. Hoping the friends that have experience to give me some suggestion.thanks very much.I just heared friends said the Nissan consult 4 from xcardiag is good for Nissan.How about it?

I also heard about that But I haven't tried it and either see it but I heard it gives good result.
