advice

I have a 2003 Tacoma with the 5vz-fe v6 with 175k on it. Threw multiple misfire and cylinder 3 and 5 misfire codes. I had just purchased the truck so I replaced all spark plugs(Denso), ignition coils(Denso), ignition wires(Denso), cleaned MAF sensor and throttle body, and installed new air...

So, i have the chance of a mint 2002 taco, 290k, mint for 8k or 2005 taco , 212k for 10k or 2010 taco , 4 door, 120k mint for 22k Damn , Heelllpppppp? :D
