I do the same trick with the automatic seatbelts.
As far as putting cupholders into the cupholder-less G2, there is hope. The '90-'95 Ford Taurus and Mercury Sable have a cupholder that fits in a single DIN slot.
Hey, it's better than nothin. If you want instructions on how to do it check out g2ic.com and do a search for "cupholder".
