Aero have said there will be full spares support when the car is released. Also i dont think cars will have moved on as much as you say, afterall this car won last years national series. Plus from what you are saying the B44 is already old hat as the BJ4 WE has already been out a few years.
I think the aero will be very good when it arrives, its the only car i know of that has been developed on uk tracks in years.
