For every person who has had problems with the car, there are many who have not.
Strut rub is a non issue on cars with 18" wheels. I have 17"ers and have had NO strut problems.
Bubbles on the steering wheel can be fixed.. Its a warranty issue. If you choose that car...... you want those caps replaced.
M6 vs A4 is a personal choice. For your needs, only you can answer that question.
How picky are you on detailing? Black shows dirt easy and swirl marks are common place if not detailed with care. That Black metallic is a sweet look in the sunlight though. Red interior will show more dirt than black.... Again.. detailing. Both colors have pluses and minuses. OTD price may be the biggest factor.
Make sure you know the factory warranty expiration dates. If they are close to expiring...(3yrs [from the 1st day the car was put in service] /36month) you may want to consider an extended warranty.
Incidentally: I DEEPLY appreciate your service to our country. I admire you for that.
