Currently, I'm only seriously racing on my top device, I made a mistake with with my second, and bought all the cars, depleting my gold. The progress has gone from 75% complete in Feb (2,700/3,591 events), to 66% complete now 66% now (2,880/4,331). I've only completed 180 events in 5 months, plus Gauntlets and Special Events, to keep the cars at 100%.

My top device has gone from 55% (2,000/ 3,591) to 88% (3,813/4,331) over the same period. Unfortunately my 6,073 is still short:
 * 100% cars (4 more) I need 1,306
 * 100% completion I need a further 8,724
 * Total 10,030, shortage of 3,957

The next cars to upgrade for 100% completion are 400+ upgrades, with little return, so I'm going to fast run out of, that's allot of  farming :)
