small car ---go around potholes................4x4 ---go over potholes........my preference is 4 x 4, but, in Santo Domingo i have driven small japanese cars many places that 4 x 4s just couldn't fit, very narrow streets, parking spots, between buildings. i have been in situations in the countryside that when stuck, myself and some local farmers just used muscle to pick the car up. i have driven small japanese cars between trees and up the mountain, places usually reserved for motorcycles..............i find the ideal vehicle to be toyota rav 4, you sit up higher in traffic, can have 4 wheel drive, small enough for tight spots, and good on 5 dollar a gallon gas. get one a little worn as you don't want to stand out as target for criminals. another great vehicle is the mitsubishi L200, diesel. not sold in the US it is a cross between a SUV and a small pick-up.....................
