Yes I am asking Aston Owners Directly, both mixed opinions. You can get that same issue with new / relatively new cars.
Example 1
I drive the crap out of mine and have no real reliability issues. I drive it hard, rain or shine, 10k miles per year, stop-and-go DC-area traffic and long-distance (6-10 hrs), track time, etc etc etc.
For an '06-7, make sure all TSBs have been taken care of and maintenance has been performed throughout the life of the car and is up to date. Those TSBs can be very expensive so make sure they've been done.
General rule of thumb for cost of maintenance is $1500 per year, which includes fluid flushes, filter replacements, etc, but does not include major items like clutch replacement or tires. That said, my maintenance last year was $8xx and the year before that was $14xx.
Example 2
I picked up my 2006 V8 Vantage 8 months ago. so far I have put $7,200 into mine. Here is the breakdown:
All four Rotors & 4 brake pads & 4 tires $3,000
Service Fluids and filters $500
Emergency Brake assembly replaced $ 1,200
Fix a seal that was leaking $250
Windshield wiper $50
New passenger side headlight assembly $2,200
I still need to replace all four sidemarkers that have gone bad $400 (V collection style)
I suspect that before the year is out I will have spent close to 8 grand on mine in one year. It's nowhere near the 1,500 that others say is typical. Honestly while I hope and pray that a few of my items were "unusual" and will not need future replacements, I would expect and plan for $3,000 to $4,000 per year for all service needs including tires, rotors and brakes.
