Heh heh...
Paul (shooomer) has had a few motors...
Including an S1, S1 Exige, 340R, M3 CSL, Radical Prosport...
What he's saying (quite factually) is there's not a lot of difference in the setup of the cars - Exige is just an elise with LSS, sticky tyres and a VHPD. There's a lot of elises out there that are in much more extreme trim than an Exige.
To make it far more user friendly, there's a few things you can (reasonably cheaply) do - the reliability and oil usage on a VHPD will always be an issue though. You
need to get the cams timed properly - will make the world of difference if you commute in it - makes it into a different car.
As for the understeer/snap oversteer issue - get the dampers looked at and the geo checked - sounds like something is tired or out of spec. Shouldnae get much understeer in an Exige (even in the wet) unless you're talking second gear hairpin push-on territory (which any car would do) Bit of driver upgrading sorts that out.
As for comfortably controlling slides in the elise - it's just because the slide tends to happen at lower speed in the elise and it IS the tyres that make it more difficult to catch. A road tyre will regain grip better and more progressively on a wet road than a semi-slick.
