The rims (wheels), can change. But it would cost about $3000 i
think? Like the steering wheel, it is also $3000 to change.
I think the middle badge of the rims is removable so ppl can just
buy the badge.
As for Honda and Acura. That's very different story. Most Acuras
look different from Honda.
Acura EL is Civic based, but it looks different. IT is made in
Canadad while Civic is made in Japan.
Acura Integra (till 2001) in North American has a totally different
design from Asia's Honda Integra. 2001 and after, Asia retained the
Integra name, North American changed to RSX. But engine and all are
different.
What i mean is, it is very easy to tell apart Acura from Honda
because honda make their design different.
As for RX300 and Harrier, they are basically the same other than
that extra mirror which i still have to confirm.
