Yes, it's a good idea to have one.
However, if you're looking at a used unit better think of alternatives FAST.
Sobrang konti ng used unit na Jimny. Closest thing you can get are the old Samurais.
Kung brand new naman, no problem.
Doesn't look good .. probably doesn't suit your college image as well especially with your friends happily revving around their Hondas and what not. But no worries, your insecurities will be long gone when it starts flooding & your friends starts asking if they could take a ride with you home because their Hondas can't make it through the deep floodwater.
GF won't mind also. Hinde na uso sa babae sumasama sa mga naka-SiR.
Okay na rin sila sa mga naka-SUV.
Why am I saying this? Ganyan naman sa college eh.
***. Cars. Girls. Repeat.
Thing is, don't be insecure if your friends go in your campus using their dad's BMW or their Honda's. Mas masaya mag-ford ng floods ng hindi ka kinakabahan kaysa sa mag-rev lang ng mag-rev sa kung saan saan and hard launching when the stoplight turns green.
Ok rin magkaron ng high-ground clearance SUV. You can take it ANYWHERE. Unlike lowered sedans, you need to plot your trip kase baka sumayad.
