A hardcore cornering track car - this superharged Elise S would be pretty nice. But as a daily - I don't think so.
The S660 is cheaper to maintain being only a 3-cylinder and has less complicated parts plus it will have incredible FC in comparison to the Lotus. RON100 x RM50 can bring the S660 to 550-600km total even with hooning. Direct fuel injection in a 3-cylinder turbo! Who would've thunk.
I guess it all boils down to what you want and need. I need a fun daily to replace my fuel guzzling family car. But daaaaamn that Elise S is sweet as f*k.
