Ive thought about possibly "upgrading" to a 4.6is.

Main concern, Is the M62 more reliable than the N62? These valve seals and smoking and oilleaks on the N62 are getting annoying.

My thoughts For the 4.6is
---------------------------
+ Comes in ESTROIL BLUE (Some 2004 4.8iS come in ESTORIL BLUE too)
+ M62 (Better stronger more reliable engine?) They both have strong points and weak points. Vanos rattle, chain guide and tensioner on the 4.6iS VS. rear main seal on 4.8iS
+ Style 87 Can be bought and fit on 4.8iS just fine
+ Much Rarer than the 4.8is
+ Some different possible interior combos Wrapping trim in vinyl and 2-tone interior is pretty easy to me. Just did that on my 03 540i MSport
+ The movie Bumer 2
+ Classic 90s mafia look (on the black one)
+ The Lovely bull bar!

- Older (Doesnt mean anything to me)
- Older firmware on the nav?
- interior trunk cover isnt a roll out but a slide instead? (not the floor) Sometime it comes off the track and the connected ends pop out. Happened to my 3.0
- No stock angel eyes Retrofit if you want them
- No X-Drive

My thoughts for the 4.8is
---------------------------
+ Newer
+ Faster
+ X-Drive
+ Stock AEs
+ Facelift front end more modern classy Luxury look
+ Probably newer electronics in Nav and such?

- N62 Engine
