If you're considering Megane 265, then also look at the focus ST which has 4 doors. The torque steer is annoying in the ST & a tad more space would be desirable. Can be purchased for low $20's.
I also have an mx5 and r33 GTST. There's a simple pleasure in thrashing the crap out of the mx5 and not having anything to fix after a day out, as opposed to the GTST which always needs maintenance. It's not as quick, but it is fun.
I regret selling my previous r32 GTR. it has a nostalgic value that I really miss & they are appreciating in value.
Here's another thought... What about a turbo ford sedan, do some cheap mods and daily/track it? Not as cool as an EVO or STI, but Parts are cheap and a good suspension setup with tyres will go a long way. Use the GTR as a backup if the daily is laid up.
