The parents obviously know nothing about cars!!!
The Ford Fiesta, your friends first choice, is German design and has the best comfort and safety specs in it's class and punches above it's weight with the aforementioned spec's and many others in bigger classes also ...
If he is worried about floods watch this :
YouTube - Top Gear Ford Fiesta Review
By the way Jeremy Clarkeson is 6'5" tall!
And as for his parents not liking Korean cars for the 'hassle factor' they are about 10 years out of date!!!
The Tucson is WAAAAAAY better than the dated Focus & new poorly spec'd ASX, in all aspects ...
My advise; EDUCATE the parents !!!
