I always do the same thing - if certain repairs will be needed soon, just do it all at once for convenience. If the new MDX has the same controls as the RDX (99% chance of that), trust me, you will not like the way everything works - it's beyond complicated, and the touchpad thing stinks - it's right above the cup holder and easily touched by mistake, which could change some setting you had no intention of changing. The lack of a visible cursor on the display screen is beyond frustrating, at least to me, and since I don't have a smart phone it really stands out. Except for computers and the internet, I'm really an analog guy at heart, prefer hand tools to power tools when it comes to woodworking, except for large saw cuts, of course - sort of how Jethro Gibbs builds those boats in his basement on NCIS.
