Hi noob welcome to HAN. btw i love ur car righ now my brother is looking for one like urs n good condition.

timing belts are critical things n hondas so find out for sure if it has ever been change my guest would b yes most likely once and it should b time again to change it now or in 10k more miles.

a nice pro paint job should b less than $1000 if ur car is an good shape and if u do painted be sure to get a unique color. tooo many greens around lol mmm n the interior i would search ebay and other places it and find some nice leather like n tan or black i seen some sell around $500 and less complete kit. tan looks good n ur car. mmm dark silver with black leather yummi

to install the tail shouldnt b much all depends where u get it install, is all about looking around before making any choice.
post pics of ur car when u can.
