Check if the timing chain has been done, it's usually good to get that done at around 100,000. Other than that, just the usuals, good oil, keep it watered, watch the tyre wear if it's been lowered on coilies etc. Cosmic is a great colour when it's nice and clean, get some Natty Blue Paste Wax from Poorboys! it will really bring out the metal flake in the paint.
