My neighbors are looking into buying either the lexus ls430 or current bmw 740il. Because the dealer is giving them such a big discount and their son loves bmw's my neighbor wants to get the 7-seies. I keep telling them to wait a few months until the new e65 comes out. My reasoning is that if they like the new car they can buy that, but if they don't like it they can get the e38 at a big discount. They said they won't want to get the e46 because the current 7-seies has "tried and true technology". What should I tell them to do?
