If you would be so kind, could you list a summary of items/consolidated list we can do to "extend" the performance of our cars? I realize I could do the leg work and find out for myself, but... These changes may be specific to a vehicle, meaning something may be doable to a DBS that does not necessarily translate to a Vantage??

Anyway, I'd suggest the list be broken down by:

Light improvements - (Low cost, bolt on, user installable, small increase in power, tuning, etc)

Medium improvements - (Medium cost, changes ride, noticeable improvements in power, etc)

Extensive improvements- (Higher cost, high performance improvements, requires professional installation, etc)
