Closing in on 30 here. I recently traded my 05 Saabaru 9-2x Aero for an 11 WRX 5Dr to give me more space for hauling around my 6mo old son.
No mods other than a few simple bolt ons. No exterior mods planned. In my mid 20s I had a Supra, 350Z and 370Z; all with mods inside and out. These days I'd much rather fly under the radar so to speak, but I still crave something fun to drive (and practical).
