hi, wtf are you talking about? LOL comparing an x5 to a SRT8 jeep LOL!!!
anyway, yes they are expensive and the dealership is used to dealing with people with lots of money and zero desire to work on cars.
and you can surely get any part that is manufactored for the car… maybe you mean at a discounted price or a chinese aftermarket… if a car is production the parts are avalible and any parts counter… you can order a drop out motor or tranny from a parts dept???
btw, “M” cars are slow from the factory, oh and btw btw, your jeep is slow as well
incorrect… but true compared to the options listed.
