I have a VX II Acclaim too and I wish I had of bought the S-Pac if only for the kit and suspension. Changing the suspension yourself is roughly $1000 (springs and shocks) and the kit would be another $2000 painted (Sports Kit). If you're looking at an aftermarket kit thats at least $3000.
So for $3000-$4000 difference and only 30,000kms, I'd change over. No kit on the base models looks **** IMO, even if it's only the S-Pac kit it looks much better. Black car also, decent trade.. do it!
