It is the time to got a new suv. I am in WA and interested in 2015 RDX AWD. Got a quota from local dealers and $34575 for AWD version. I know some shared prices in autopriceshare are better than mine. However, I feel OK as this price is already lower than invoice. The dealer also recommend me to purchase a 4 year prepaid maintenance package($2000). I haven't own a Acura before and don't know the maintenance cost for RDX. Should I select this prepaid maintenance packages? any suggestions?
