Hello and welcome.
for a first car a skyline is awsome.depends on how much dollars you have. you can pik up a nice R32 GTST for arounr 15 - 18 grand.
They also come in 4WD ( GTS4 Version , also turbo ).
but the normal GTST is RWD. the only differnce i would say is 4WD would be a bit faster and would handle better , but cant do burnout . and the RWD would be more dangerous , unstable in the wet i suppose. but its all up to personal preffernce and also comes down to the $$.
Thanks, hope this helpd
