evening guys :-)

i recently bought a 1998 bmw 316i im currently using it as my little project (modifying it and blacking it out)
however since ive bought it the starter motor is on its way out and occasionally requiring a bang to start it up
im picking up a new starter on saturday however this is my first bimmer how difficult is the starter to remove and fit?
also taking a look at the parcel shelf putting 6x9s looks to be hassle! also can anyone give me any smaller things to do
that will make it look better when it comes to blacking it out? (apart from window tint and spraying the alloys) can anyone give me any info?
