i dont mean to diss the 5s its just it has really brought me nothing but trouble...even though some is partly my fault...my celica being my first car and all i luv it to death but my car has been out of order for about 14 weeks now and the parts cost me over 1200 so far and i still have things needed to replace and after i put it all back together i still dont know if it will run right...but if it all gets back together sometime in the near future you bet i will be putting aftermarket parts on it. i just wont expect much.
