a friend of mine just bought a 06 bmw 325i just like yours he got it for 37k ....but now he wishes he would have gotten the 330i... any way yes tint them windows ASAP... it actually increases the value of your car in the long run...
non metallic tint tends to fade quicker, the more metal it has in it the longer it stays black
looks nice and just so you know... when we were going to do the system in his 325i the dealership told us it would void the warranty... so no system for him
don't ya just love them free oil changes and 100% warrantied replacement parts?
