Nothing.
Excellent fuel efficiency for a 4 wd vehicle (30+ mpg always).
Good all round duel purpose vehicle.
A little noisey over 70 mph - a little extra sound proofing sorts that though.
I cannot understand why, for the life of me, Daihatsu stopped making these. It's madness. What an economic blunder. Mind you - perhaps they were too good and turnover was too low!!
