i've developed a mk1 MX5 as my track toy as it's easier to be a hooligan with FR. That and the fact an Elise has very expensive clams to fix if i hit something! The Elise is now road only where i enjoy superlative feel and incisive handling within its limits. It's good to have both though, quite different.
i wouldn't judge a fun/driver's car just on how quick they are. there are challenges to MR and RR that make life...interesting.
