If you're actually asking a question, you need to provide a little more detail...

You'll see quite a few Japanese companies which have similar names to other ones due to the syllabic Japanese language (words are made up of syllables rather than distinct letters, so there are only so many combinations), or because they are named after their founding (and many people/places have similar names, also due to the syllabic nature). Both Aisin and Aisan get the first half of their name from the Aichi Prefecture (a Japanese province) they started in, it gets a bit complicated after that (Japanese is a strange language, you can have individual syllables that are pronounced one way but when combined with another are pronounced differently, so the San part of Aisan comes from Mie Prefecture (both san and mi are related to the number three). Aisin comes from when Aichi Kogyo (Aichi Industries) merged with Shinkawa Kogyo (Shinkawa Industries) to form Aisin Seiki (Aisin Standard, or something similar). Another good example is that a lot of Toyotas will have Mitsuboshi (Three Stars) accessory belts, not to be confused with Mitsubishi (Three Diamonds)

Aisan (not to be confused with Aisin by the way) has been an OEM supplier for Toyota carburetor, throttle-body and fuel-injection components since the '60s. Unlike Denso and Aisin though, they're not actually part of the Toyota Group (but Toyota does have a financial interest in them)

One of the only things working against (or for, depending on your viewpoint) the ST204 Celica is that a bunch of them were probably crushed as a result of not being able to source replacement airbags during the Takata recall (a similar fate befell the Starlet). I don't think all models had that particular airbag though so it probably disproportionally affected certain trim-levels too. This might artificially inflate the rarity of what was generally seen as a nondescript uninspiring 90s hair-dresser "sports car" that still sold reasonably well.

That one is in no way indicative (GT4 engine conversion, and is over-priced for a genuine 1-of-77 Aus delivered GT4 anyway, let alone a conversion), and there are a few ST204s up at the moment, varying from reasonably priced (5-10k) to ridiculous. At the end of the day, a FWD Celica just isn't that "special" a car, especially with an auto.

Swap the driver's and passenger side globes, see if the problem travels (that will 100% confirm whether it is the bulb itself or not). Are they a combined dual-filament globe (probably H4) or separate globes for high and low? With the combined bulbs you can get some funny occurrences, I had a scenario on my old AE102 where the brake light would come on when I press the pedal, the tail-light would come on when I turned the headlights on, but if I did _both_ then nothing happened (turned out one of the filaments had broken and was shorting out on the other

The irony of what appears to be a spambot replying to an 18-year-old post with a link to "Sell any car fast"....

You'd most likely need some kind of RFID-blocker (either a box to put everything in, or a pouch that you put the keys inside and then inside a normal lock box), can't imagine these would be too hard to find given how paranoid people are these days.

There's no such thing as a Rav4 GR. There is a GR Sport, but like most of those that is just a bodykit/trim/sticker package, maybe with better wheels and slightly firmer suspension.

Depends on your definition, there was an Atara SL in the XV50 series that was built in Australia (XV50 so same generation as the RZ), the Atara name was dropped when they moved to the Jap-sourced XV70 series in late 2017.

There are two handbrake shoe pairs in total, one for each rear wheel

Drive-shaft oil leak (if coming from the diff oil seal area) would be transmission fluid, not engine oil. ATF and PS fluid are very similar (and some cars will run ATF in the power steering system anyway). If the "driveshaft leak" is from a CV/tripod joint then it would be grease, very different to both engine oil and PS/ATF.

For the oil filter just go with a normal Ryco one, never had a problem with them on Toyotas and they're readily available at Supercheap etc.

Wheels/tyres can make a big difference too, the RZs run 18s whereas the SLs are only 17s (which for the same overall diameter means more tyre sidewall for a softer ride).

I'm talking about replacing the actual guts of the motor, you'd re-use the wagon housing to retain the mounting. Both housings may actually be the same anyway, with the only difference being the shape of the "grommet" to suit the angle/curve of the rear quarter panel
