Modifying??

[MKnight702]

I'm tempted to join the Caterham fold. However, one thing I want to know before I take the plunge is the view of modified cars. I'm not talking about adding Halfords tat but engine mods to improve power over standard etc.

The cars I see advertised pretty much all seem to be "stock" as they left the factory spec, but I like to tinker and would probably end up having the head modified, upgraded cams, fitting throttle bodies and getting the car remapped to suit as and when the upgradeitis struck. Would this have an adverse effect on re-sale? I know that I wouldn't get the value of the mods back, but would the car end up worth less than the spec that it started??
