650i or 645ci?! So hard to pick! Help!

Hey guys,
once I get my truck sold I will be getting a 6 series for sure. Just trying to decide if I should pay about 4k more foR a 2006 650i or just go with a 645. I will have about 28k to spend... So I'm thinking I WOULD be able to get a 650i if I looked really hard, and a 645 would easily be in my budget. Is the engine different THAT great? Is it easy to tell the difference? My guts telling me to go with the bigger engine but it'd be nice to have some extra cash after the purchase for wheels etc. Please let me know what you would do. Also, for those that have driven both, how much difference is there btw engines? Is the 645 still quick? Thanks in advance for all the help!

I find my '05 645 to be plenty quick. Not sure the actual HP difference is, but I think a warranty (If the 650 you'd find would have one) would be a stronger attraction than a couple extra HP.

get what makes sense to you... make sure you set aside some cash for repairs and a new set of tires (most 645's will need new tires by now unless they just had new ones put on)...

but make sure to test drive and get repair histories of the car you plan to buy (your local BMW dealer can help if you tell them you intend to get service through them)...

lastly make sure the brake jobs have been done as that can cost you more than a grand...

Warranty, tires and maintenance should be the biggest factors. If all those are equal, start looking at the cool bells and whistles on the newer models for sure.

Ok sounds great guys. Thanks for the help. Anyone have experience with a 645 and 650? Jus curious if there is a noticeable difference between the engines. Also, do all the 2006's and up have keyless entry?

Just traded in my 645 for a 650. The difference is noticable for me in the power but don't get me worng, the 645 does haul ass. all are keyless entry, unless you are referring to the cpmfort access feature. Not all comes with the comfort access feature. Either one is a good ride but like others here have said, warranty is a big deal because the maintenance can be expensive.

What is the difference btw keyless entry and comfort access? Which is the one where the car unlocks when you walk up to it and you can push button start it without getting the key out?

Comfort Access is the one where you do not have to take the key out of your pocket.

Ok sounds good. It's good to know there isn't a major difference in power. I guess I'll get the car that fits my needs best and not worry about engine size. Thanks for all the help! Any major features the 2006 would have the 2004 wouldn't?

Warranty, Warranty, Warranty. The '05 645 CPO's will be close to or out of warranty next year. To me the warranty is the most important feature. I don't feel you will see that much of a performance difference between the '04's and '06's. Just my opinion. Best of luck in your search.

Is the 645 still quick? YES

Is the 650 still quick? YES

If quick you desire, go ahead for the M6 HELL YES!
