S Series and Track Days

[Qualia]

Hi,

I've been lurking for a while and I am amazed at the wealth of information available on this site. Excellent!

I am thinking of buying an S Series, most likely a Ford engined one. It will be a second car for weekend runs and Track Days. And that's the question: How useful is an S Series as a track tool?

Apart from the fact that an S is invariably quite an old car, how do they handle? How do they compare to something like an Elise? Any essential upgrades to consider before going trackwise?

Many thanks for your advise

Andy
