differences in sline b7 a4

[thejimrose]

hey all - so i'm finally thinking of selling the ol b5 and getting
something newer. will have a 60 mile rt/ commute in a week [up from 5
mi r/t now.. ugh]. looking at a3's, a4's...

wonder if anyone knows the 411 on the a4 sline improvements? obviously
wheels and bumpers, probably springs and shocks.. but anything else?
steering wheel, seats, etc?

trying to gauge if it's worth it. wheels, suspension will get changed
day 1 so i'm not concerned. bumpers are easy to change, seats, not so
much.

anyone know of a manual wagon anywhere?

thx
jim
