Samurai is a fun! Samurai is cheap! Samurai is tough! Not quite an investment, but you have to shop pretty hard to find a nice samurai for under 1600 on the west coast.
If your mom is worried about safe, you'll have to assure her that the Samurai is a lot safer than a motorcycle or vespa.
You can tell her that she'll never have to worry about you drag racing.
Let her know that driving a samurai will teach you humility. It's humbling when you learn that the slow lanes were built especially for you.
Best not to talk about the chicks who dig body damage.
On a serious note:
the samurai is not a car. It needs to be driven safely. Old Jeep, montero, fj40, or samurai it does not matter, these short, tall, narrow vehicles are not cars. They can be quick to punish the mistakes that inexperienced, inattentive, or reckless drivers make.
The samurai rollover risks pretty much confirm this:
1) Alcohol
2) Inexperienced drivers (did any one over 40 die?)
3) first six months of ownership
