have a used car 1-1/2 years. Is it good idea to pay off loan if able?

if you are able to pay off, yes it is good idea. get rid off the loan and free yourself and mind.

If you pay it off now, the money that you would have to have used for repayments can then be savings. Live with debt for the shortest time will save you in the long run.
Good luck

Of course, you'd save yourself from paying the interest charges. That is, if it is a simple interest loan.

It is ALWAYS best to pay off a car as soon as you possibly can. The longer you take to pay, the less the car is worth - Suze Orman recommends not financing for more than 3 years so the value is in line with what you paid.

no
keep your self in cash on hand

well if you want to, and have the cash, yes, its always a good idea to pay off any loan, but dont go broke if thats all the cash you got, or mabey put half of that on the loan and just pay payents agian, but the car will be paid half way off soo your payments are lower every month!
