Congrats on the purchase and welcome to the site (I see this is your first post)! Glad to see we've converted another one. Now go and tell all your friends to do the same
An airlid is a quick and easy upgrade. You might want to do a search and read up on the free mods, or go here: www.installuniversity.com
The mods you perform are only limited to your budget. If you want some ideas, you can check out my site to see what mods I've done to my 'bird. All my mods to this point are just bolt-ons (except for the gear swap).
Look to the site sponsors for the parts you need----------->
