Best for me, because this is what I owned:
EB2 SXR8 - Lovely car, nice seats,
ABS, 4-speed auto.
AUII XR8 220 - Had a lot of Tickford options. Independent rear end fantastic.
BA GTP - My favourite, tough looking. This one was manual. Oh, that bulge!
FG R-Spec - So fast, Black/Red great looking. Engineering detail in door seals a highlight for me.
Worst, because I actually owned one:
EA S with 3.9 MPI. Worst car I owned, turned me off Falcon 6’s. Got rid of it for the EB2.
