Hi Everyone, Looking at adding an A45 to my E63. The wife has fallen in love with it after her test drive, must admit I was very taken by it also. Just wanted to get a concensus on what any A45 owners thought were good optional extras and which weren't worth the money. Also, anyone got any tails of woe with regards to running 19s over 18s. The demonstrator we took out had 18s on but the dealer told us the 19s can make the ride a little crashy. Appreciate any feedback you can offer.
