All trac numbers were extremely small....My cousin owns one of only 49 93' all tracs imported into the US. If I remember correctly overall All trac numbers 88-93 totalled less than 9500. The other major issue was that they did not sell well at all (they were more than a MA70 turbo in some cases) so the factory kept many of them as demos, pool vehicles, and company leases. I can remember being a kid and my dad bringing home All tracs all the time from the Demo fleet.
Definitely the all-trac. Guy I bought my mk3 from sold it in order to put a lot of money into his newly acquired, completely stock and mint all trac. Beautiful looking. CT26 going in. Gonna be a great auto-cross car. I think the 500-100 figure is correct ... but I think it may just be 500.
There are only around 1500 total ST185 All Trac Celicas as far as I know, I wanted one for the longest time and just finally settled on a 1g DSM AWD because I wanted something along those lines for a winter car/dd... they are EXTREMELY rare, more rare than the MKIV or the MKIII...
I believe it's 504 in 88. I had an 88 for awhile, fun car, sold it to a friend. Just too hard to find stuff for, and it had some problems. We put a clutch in it a few weeks after I sold it to him, what a nightmare job that was, engine and all had to come out and was still a major pain to seperate the two after they were out,and even worse going back together. Fun to drive,not fun to work on.
