So, just messing around looking at SRX values on KBB.com - it seems that Magnetic Ride Control adds no value to the used car price, with or without MRC is the same? Does that sound right?
Also interestingly, the 3rd row seating on a 2006 is one of the most expensive upgrades, adding ~$1,000 to the blue book used value. Way more than the V6 to V8 upgrade, 2WD to AWD, Towing Package, Premium Wheels, etc. fwiw
