advice po mga peeps..

I have an 03mdl revo diesel GL variant.. recently, I have replaced 3 new tires, brake pads and 4 ball joints.. pero lately, may tunog sa baba... the mechanic cant seem to figure out where the tunog is coming from...

my bro offered me to swap with his 08mdl picanto with just 1300 mileage.. sariwa pa masyado... I'm opting for the swap kasi I feel like my revo is starting to show signs of old age...meaning repairs are coming...

Some say revo is easier and cheaper to maintain than picanto... and that after few years, the 08mdl picanto will depreciate more in value than my 03mdl revo.. totoo ba?

is this a good swap for me (from revo to picanto) ? or should I just stay with revo AND fix whatever problems I will encounter?

Thanks in advance
