I totally agree, my goal is a fun handling car. Not a contender. Maybe after a few years I'll worry about a contender but trying to outdo top 10 cars requires more time and ability than I have at this time.
After the GRM it'll turn into a DD. Heck it'll be a DD before that too. With autocross etc. like you said, I'm just out to have fun with the car I dated my wife in. lol.
Glad to see that you have a realistic view of the world.
One more suggestion: don't go nuts with the swaybar and buy the biggest one you can afford. I found that was detrimental to handling and the car is much more predictable now that I dialed it back.
