Well, her plans are to tidy her up a bit first (faded plastics, deep clean) get some service work done (bearings, oil change, filters, timing belt, plugs, etc.), Then start on styling and tuning.
On the styling side she's already got wind deflectors (who hasn't), but going to get a sunroof deflector also, as the noise is horrendous, but it's so nice having it open. She came with the optional extra MOMO alloys (but will need a real refurb as have bits of damage and only been sprayed without filling and smoothing), and I miss the winky faces shed had so getting some for her, and I don't have any ideas beyond that, untill I have money for Glanza body parts.
As for modifications, got a pipercross panel filter, got lightweight water and alternator pulley, have a 5e-fhe full exhaust (manifold to tailpipe) to pick up this weekend, then need to source 5e-fhe throttle body (or 4a-fe), 4e-fe tubular intake manifold, certain set of corolla (or Glanza) injectors, piggyback ECU (emanage blue probably), and humming and haring over whether to take a risk on blown coilovers and trying to rebuild them, or just get springs as need comfort and height when heavy laden, and then go from there.
Got ideas, just need money and to source parts.
And the GLS come with better interior in a lovely colour, same on door cards, clear corners, rev counter, chrome trim in various places (handles, grill, window seal, dash, door cards), can't remember what else, but the interior alone and rev counter make a huge difference, and Chrome door handles make a subtle but nice look. GLS is top spec for a reason, that's for sure.
