98/95formula

I have two cars i need a little help with.
the first is a 95 formula a4 t-tops 3:23's black with graphite int.
i am looking for a little help with production numbers to see how many had these option's and came in black..
the other i have some info on
98 formula
w55 mon am/fm cd
u81 bright red paint
t-tops
2:73 gears
A4,with the twist top painted rim's
factory keyless entry
if i did the math correctly by % i come up with 66 cars in bright red with these options in 98
can some one help me to see if this is correct or if i failed my math quiz,
the 98 has 91,000 original miles and looks great i paid only $6,000 for the car
do you think it was worth that much???

According to the sketchy info I have on '95s.......

7448 total '95 Formula coupes built
4889 had A4
1662 had 3.23
4342 had T-tops
35 had chrome wheels
3210 had Cass/EQ
2804 had CD/EQ
?? were black
?? had graphite cloth
1432 had graphite leather

On the '98........
A4 w/ 2.73 = 942/2123 = 44.37%
Red = 397/2123 = 18.7%
T-tops = 1567/2123 = 73.8%
Keyless = 1800/2123 = 84.8%
W55 Cass Monsoon = 1816/2123 = 85.5%
Painted rims = 1460*/2123 = 68.8% (*2123 total - 221 WS6s - 14 1LE - 428 chrome whls = 1460 painted wheels)

Estimated % w/ this combo = 3.05% = ~65 cars. Of course this assumes these options were evenly distributed w/ all other options, which might not be the case (for example, ALL RED Formula coupes may have been A4s w/ 2.73s, which would change the percentage to 16.3% or 346 cars).

I'm pretty convinced my cars a 1 of 1 (or at least 5 heh) Leather, 6 way adjustable driver/pass seats (4 way electric), 10 speaker CD player, 3.23. As said, sketchy info on the LT years, but I've not seen any numbers on 10 speaker equipped ones.
