you are worried with the tax dept? or you think you might suddenly gain more money to settle the loan faster in recent months to come?

you can always do early settlement with a car loan as far as i understand as there is no rule to say you need to wait until how far into your loan before you do an early settlement...

that being said... i believe you might lose money to the bank via the interest as the interest are most likely not refundable... maybe you might gain by settling 2-3 years early in a long loan but definitely not 6 months out of a 2 year loan...

even if you look at flexi HP loans like the hong leong cruise control...they only allow you like up to a maximum of 30% of total amount loaned if i am not wrong in the current account which you can accumulate money to settle the loan earlier...
