im looking to buy a b18b. ive been searching and i found this site cnsmotors.com/acura.htm on this site you can get one for like 1,000 bucks including shipping cuz im in cali. reading the faqs on the site they say they have no way of knowing how many miles there are on the engine because they're from japan. what do you guys think. it seems like an extremely cheap deal. is it too cheap and is not knowing how many miles on the engine a red flag?
