ive only had mine about 2 months but am very pleased with it,im also a mechanic so i do all my work myself.
as someone has already said because its a RS the prices of parts are slightly more but you expect it on a cars like these.
im very pleased with mine and i thinks its quite good on fuel but obviously wen you start booting it around the fuel does drop quite quick.

1 other thing to rember is they need to be run on 97+ octance fuel (super unleaded)
