Yes its diesel, now cry u lost
if your wanting to keep the miles down (or even concious about the miles it does) then your obviously thinking about when you come to sell it and the money you will get back on it.
on this basis, i would NOT mod it as you will get more back for a un-molested car. Perfect example is alot of members on this forum bash on about how it should be OEM and left alone etc etc. Tho saying that there are also alot of people that like to buy an already modded car. Leaving it un modded will save you money in the future.
Now to many mods to list! Lots of power, torque and Leather!
