Going to look at a couple of abbeys on Saturday one is a 2006 aventura 320 the other is 2008 vogue 520, there's about £1000 difference between them, we were just looking at year but is one a better spec than the other? If both are in the excellent condition stated in the ad which one would you choose and why? They both have motor movers and covers , the vogue also has an Isabella winter porch awning.
