All depends on what ya budget is
if ya've got access to pure money, ask around body kit manufacturers if they'll do a one-off kit for ya car
if not, do what I'm doin with me Fiesta, mix and match kits, I'm gonna be havin bits n bobs from a few companies.
again, all depends on ya budget, more money, then ya can get ya lights smoothed into ya rear end i.e. skyline stylee and you can get a headlight transplant (take headlights off another car and fit them onto yours)
Not as bigger budget - headlight masks and new rear clusters
I've got pure ideas for mine, so if ya stuck ask me and i'll see what me imagination comes up wit
