If you are going to keep it and modify it for a long time then store it. The way you go thru cars I would just beat the piss out of it and have a blast. I had more fun last year in the snow in my WRX than I did driving it the rest of the year. Besides you can always trade it in for a newer model…
Besides, I will miss the entertaining threads of “OMG SHit almost just hit a tree/dumpster in my sti in xx parkling lot”
