i know some of these questions don't go down well.
i'm sure the ed30 with the better internals, turbo etc. is the better car, and even at standard i'm sure it's alot more efficient in putting across the power, i.e. midrange kick etc.
as said if budget permitted would prefer to get the better option from standard.
just doing a bit of research, as looking for something with a bit more space in the near future, to replace my much loved 2003 audi tt 225 coupe quattro (so budget will be similar value to mine)
the mk5 golf form seems to fit the bill.
