Hello! First post to this forum - glad to find you here. I'm starting my search for my next vehicle and I'm trying to decide between an '01 GS300 or an '01 530i. Curious to know if anyone here has owned both? I do quite a bit of highway miles and I've heard that the 530i will get 30mpg on the highway - how about the GS3? I would imagine reliability would go to the Lex, but then again, consumer reports rated the e39 5 series best car ever? Appreciate any insight you have.
