i really dont feel like going and getting mileage, year and price's for each car ive listed and compare it to the sti, sorry. my whole point is just that the wrx and sti are not the only awd car out there despite what all the skier/snowboarder bro's and ken block lovers think..
i know plenty of kids with wrx's and a couple with sti's, wrx's were all over our school parking lot. but out of the people i do know, the only ones that were reliable were the newer or lower mileage ones. one guy blew a motor at 100,000 miles, has had to get his clutch replaced twice, another is on his 3rd transmission, and every one that i know of who has modded them is having problems. not to mention that every one i drove that was decently cheap had atleast one major problem. now like i said, the newer wrx's seem to be better, though they have less mileage, ive heard good things about reliability when compared to the older wrx'si just feel like its hit or miss with subaru's sports cars.
as for audi's reliability, id agree with you in most cases, but like subaru, they are kinda hit or miss, but with different models, the 2.7t cars, were terribly unreliable, while the 1.8t's and newer 2.0t (i think?) seem to be very reliable. their older early to mid 90's cars are also very tough and reliable. i know someone with a b6 s4 with 110,000 miles on it and he hasnt had anything go wrong other than wear and tear items.
as for bmw, id have to say your wrong. again, not every model is going to be extremely reliable. i own an e30 with over 220,000 miles. ive had it for 3 years and havent had one single problem. and i drive the shit out of it. i still have the engine near redline all the time, ive jumped it alot, treat the transmission like shit, and nothing. ive got a friend who works at a bmw dealership, and he says even their newer models are bombproof. now this is just coming from one guy, but everything ive heard about them has been the same.
