I am very excited to be in the market for my first Lamborghini, and I have decided on a Performente Spyder. Am I correct in noticing that I cannot get the lift system WITH the magneto-rheologic suspension system? It also looks like that is the case with the 610-4 as well, correct? If this is true, how essential is the magneto-rheologic suspension system? I feel like I have to get the lift system for basic curbs, etc. Any thoughts or experience, please? Can they be custom ordered together?
