i do about 70 miles a day and i do get annoyed by the road noise, and sometimes getting stuck in traffic makes me feel like i should get an automatic. i was thinking to myself to maybe get an older e39 525d/530d, whcih is probably much less economiical but it will probably be much more comfortable and relaxing to drive those cars were designed for motorway driving and have very good sound insulation
but then you have done alot of mods to your focus so it must be hard trying to let it go!
a5 is technically better as its higher in spec but if its alot more in price dont worry about it. your car was designed to work with the A1 spec so itll work fine, however if you can get it the same price then why not
