Agree with Abz here.
Car looks spot on the way it is, engine compartment looks fine too - money spent here on flashy bits are a waste IMO. Interior is where I would consider spending money and on maintenance (Oil, LSD, V160, Brakes, etc... - when and if required)
Personally not convinced that the facelift rear lights will suit your car - I think they look nice on grey or white cars and perhaps Red.
Wheels are a personal choice - ones you currently have look good, although a set of TTE would give the car a slightly more aggressive yet classic look.
