Ok, i deduce that he does not need space as you have mentioned
in your first post. If he does not need space. GT-R would be the
best of the lot. Big cars and good handling doesn't often come
together. A GT-R has 2 doors. How would your dad fit the whole
family of 5 through 2 doors? It's possible yes. But I'm sure you
guys would not like squeezing into a confined space for a road trip
to M'sia. I would rather take a coach there instead!
If he needs a good compromise between power+sporty handling and
space. EVO X would be better. You could also consider the Subaru
Legacy. It's more spacious than the Evo but a little down on power.
Nonetheless, the Legacy is a powerful car.
But if he needs to fit all 5 of you in comfortably. I'd suggest he get a MPV or a
large sedan. Choices you could consider -
MPV: Honda Oddesy, Toyota Estima/ Previa, Toyota Alphard (it's
huge).
But it seems that your dad having a war against MPVs
So, here's a list of Large Sedan cars (which aren't
MPVs) and have a reasonable power to weight ratio.
Large Sedan with reasonably powerful engines: Honda Accord, Lexus
GS300, Toyota Camry, BMW 5 series, Mercedes E class, Audi A6. There
could be more that i haven't thought of. As you can see, there
ain't many Japanese cars to choose from. Europeans generally
produce more large cars. I personaly like the Lexus GS300. Spacious
yet sporty.
Get a sports coupe if he needs a 2nd car. Maybe GT-R for Japs and
M5/6 for the Europeans. C63 AMG would be very nice!
I hope this list helps as it's really hard to understand what your
father wants in a car.
Take note: A fast, nimble handling car
does not come with much space. Make a compromise between
space or speed/ power.
Now, choose: Speed or Space?
