How much should a 1985 Honda Prelude with 166,000 be worth ?

well the price u could pay is no more then $1000 if u are willing to put new after market parts in it (close $5,000 and above) you could have a nice car and on the test drive check if the steering wheel is shaking (vibrating) or the sound of the car, look if it starts the first time, when driving also look if all every thing works in side and be sure that the car has not a lot to do, and it can maybe last another 200,000 miles but its about how you maintain your car i owned a Honda minivan ran it 340,000 and when i sold it it was like it could run another 100,000 but the inside went through hell and back so ya i mean its up to you, do you want to take care of a car or just run it till it dies

I don't care how well he's maintained it....it's a 28 year old car. It will break down sometime soon, and parts are going to be VERY hard to get. Don't pay more than $500, if that.
