which cars' aftermarket parts have potenial for good profit

[clueless]

if i was to sell aftermarket parts for cars, what cars do you think would be good to do?

for example, civics has a huge aftermarket, and therefore, it's hard to sell their parts and make good profit. And for 240sx, the parts are rare and it's easier to sell stuff for more and make a better profit.

But what other cars are good to do aftermarket parts for?

Thanks.
