You would do better to save your warranty premiums in your own savings account.
Warranties are a gamble. You're betting you're going to collect - the warranty company is betting you're not. In any case, they win.
Cars as old as yours are more subject to equipment failures and the warranty company will price the policy based upon that fact. You'll actually be paying for repairs in advance, betting that you will need those repairs. If you don't, they keep your money and you get nothing.
Warranties don't cover wear and tear items - and THEY define what is wear and tear. Some are obvious (belts, hoses, tires, etc), some are not (wheel bearings, friction surfaces is a common term they use for brake pads/shoes and brake jobs in general and the clutch, etc). Warranty companies almost always fail to cover repairs due to "failure of the owner to maintain the vehicle". Also, on top of your premiums, you'll have to pay a deductible. Example, you pay $80/mo for the warranty. In two years, you'll have paid about $1,920. Then for major repairs, you may have to pay $500 deductible. If that major repair was the transmission, you'll have paid $2,420 - the cost of the transmission anyway. Additional parts and labor are not covered. So add about $200 for transmission mounts, transmission fluid, etc).
